i am using 'Bat to Exe Converter' to convert my batch files to exe format.
Now, i am running into some problems.
Whenever i convert something, and i set 'Working Directory' to 'Current Directory', and i start my exe in echo on mode, this is what i end up with to check if there is a specific file in the directory of my exe:
the actual command: if not exist "%~dp0\file.txt" goto :nofile
output: if not exist "C:\Users\MyUser\AppData\Local\Temp\4CBC\\file.txt" goto :nofile
Can anyone help me with this? I don't want it in the temp directory, i want it to be in the directory of my exe.
Thanks.
Without having Bat to Exe changed by the author, I think you have two options:
Remove the need for accessing %~dp0
Perhaps you can merge file.txt with the include option of Bat to Exe into the EXE file. If so, "file.txt" will automatically be unpacked in the current directory when running your compiled exe, and you can it access by %CD%\file.txt.
Get %~dp0 from outside and pass it to the exe as a command line parameter.
This can be done by a simple starter bat file that resides in the same directory as your compiled main batch file. This script schould contain the line
YourCompiled.Exe %~dp0% %%*
Your compiled exe then gets its directory from %1. So you cannot pack everything into one exe, but the main portion of it, perhaps that is sufficient for you.
Well, apparently your batch to exe converter simply packs the batch file and extracts it to a temporary directory prior to execution. Very simplistic, hard to get wrong (compared to actually understand the batch file) but it introduces errors such as the one you're describing.
Your best bet is probably to use another batch to exe converter; some of them are actually a little more sophisticated.
Generally, this is not a good idea. firstly, its prone to errors and instability of the converter on different cmd features. secondly, a determined hacker can still decode what you are doing with the batch. My suggestion, if you are so afraid of people looking into your batch,
1) let only the people who are authorized to use your batch to use it
2) give them the correct permissions.
OR, don't use batch at all
1) create a central interface such as a web interface, where all tasks to be done goes through that interface, like using an ATM machine where only buttons are allowed and all the available user options can be done by pushing buttons...etc..
2) authenticate your users through a central authentication system, eg Active Directory, or LDAP or a database.
This is an 2.5 yr old subject but there is an answer to this so I'm posting for anyone else that happens to find this in a search.
B2EC written by Fatih Kodak, has an option to "Submit current directory".
When this is used, you can reference %1 in your batch file to get the path of the EXE that was executed (instead of the path of the extracted BAT that is really being run).
Hovering over that option in the UI shows "Submit the current working directory as the last parameter". The "last parameter" in my use has always been %1 but you can test your code to be sure.
The latest version, 2.1.4 at time of writing, of Bat to Exe by Fatih Kodak creates an Environmental Variable at runtime that can be substituted in place of %~dp0 to reference the Exe's path. Therefore, you can simply replace %-dp0 with %b2eprogrampathname% in the original batch file.
You can use external folders with f2ko's batch to exe converter. Having
a separate folder for subroutines can neaten up a project folder.
To call mysubroutine that is located in mysubroutinesfolder\mysubroutine,
...
pushd mysubroutinesfolder
call mysubroutine
popd
...
The call can be made a one liner:
call xqt mysubroutine
where xqt.cmd is a program that does the call for you:
pushd mysubroutinesfolder
call %*
popd
exit /b
(the %* means "all of the arguments").
In this way your batch programs run as batch, and UNMODIFIED they will
compile with the bat to exe converter, creating a completely folder independent executable. Select "temporary directory",
and include all of the subroutines/executables in your mysubroutines folder
by "selecting them all" with your cursor as usual, then hit "copy".
Be sure to include the xqt.cmd program too; place it "outside" of your mysubroutines folder. Make sure that is is accessible by your main program. Remember to select x64 if you
are runnning on a x64 machine, or the executable will not find SYSTEM32
files. You can find f2k0's batch to exe converter at:

%cd% will give you the current directory:
if not exist "%CD%\file.txt" goto :nofile
Use %CD% instead of %~dp0.
EDIT:
B2EC is not a real converter. Creation location of equipped .cmd file was chosen to be %TEMP% and this is a good choice. Application just lacks 3rd option for working directory of the script - .exe file directory. I advise you to mail the author about adding this one.
Different paths for .exe and created .cmd lead to information loss, i.e. we are unable to know .exe directory and current directory at the same time without providing additional information to the script (e.g. using environment variable or passing it as first/last argument to the script). This script would need to handle it and we would end writing cmd scripts tailored for this converter, which is bad.
%~dp0 - script directory (%TEMP%/.../) - practically useless
%cd% - working directory (as set up in the converter) - currently there are only 2 options: current directory (working directory of .exe) and temporary directory (actually equal to %~dp0, but without trailing backslash)
I think it can be solved by patching cmd.exe instance in memory to change the script path, but that's B2EC developer's duty.
Side note: Normal executable files can be easily executed with specified 0th argument by providing appriopriate lpApplicationName and lpCommandLine to CreateProcess function. Command files are executed via cmd.exe, so 0th argument cannot be set this way.

When I was trying to get elevated rights for my batch script, when I found two related SO questions
How to request Administrator access inside a batch file
How can I auto-elevate my batch file, so that it requests from UAC administrator rights if required?
...that led to answers that worked partially. For some reason, I had issues with command line passing for file path arguments containing spaces within the VBS script, so I tried to break the solution into 3 parts and concentrated on the inner (VBS) step, then adding the last step by calling a batch from that VBS which could not be found, despite in the same folder as the VBS script. I found that drag & drop isn't "that easy" and that it's different when using .vbs instead of .bat or .exe as drop targets.
Here is my actual question:
If I drag a file and drop it onto an executable (exe) or batch file (bat, cmd), The current working directory is determined by the source of the dragged item. Its directory is set as the working directory for the program or script that processes it.
If I drop a file onto a VBS script, it's different. On Windows 8.1 x64 I observe it to be C:\Windows\System32 even if the argument resides in the same folder as the VBS.
I can simply use a batch file (as drag'n'drop relay) like this
my.vbs %*
to get "the normal" .bat behaviour (drop source dictates CWD), but I also want to understand it.
Is it a bug or a feature? Is it consistent over all Windows versions?
edit: added the background (on top) for the question showing how I got there (+minor corrections)
After some API monitoring, this is what I see
When you drop a file over a .exe file the explorer.exe uses CreateProcess API function to start the process, passing the executable as lpApplicationName, and the executable and dropped file as lpCommandLine. The lpCurrentDirectory is set in the function call by the caller process to the folder containing the dropped file[1].
When you drop a file over a .cmd file the explorer.exe also uses CreateProcess API, but in this case the lpApplicationName is null and the lplCommandLine contains the batch file and the dropped file. lpCurrentDirectory is also set to the parent folder of the dropped file[1].
When you drop a file over a .vbs file, ShellExecuteEx is used and the lpDirectory field of the SHELLEXECUTEINFO structure is null, so, the process created inherits the current active directory of the parent process. By default the current active directory of the explorer.exe process is %systemroot%\system32, but it is possible to start a explorer instance with a different current active directory that will be inherited in this kind of drop operations.
[1] If we drop more than one file, the path of the file passed as first argument is used
note just for information: to test the active directory inherit the process followed was:
Open a cmd instance and change the current active directory to c:\temp
Kill all explorer.exe instances
From the cmd instance call explorer.exe. This explorer instance has the active directory in the cmd window as its current active directory.
The Arguments property holds the full paths to all items dropped on the script, so you can determine the directory of each dropped item like this:
Set fso = CreateObject("Scripting.FileSystemObject")
For Each item In WScript.Arguments
WScript.Echo fso.GetParentFolderName(item)
Next
Assuming that the working directory would be defined by what is dropped onto a script is a misguided approach. If you require that logic you can implement it in the script yourself, though, e.g. like this:
Set fso = CreateObject("Scripting.FileSystemObject")
Set sh = CreateObject("WScript.Shell")
For Each item In WScript.Arguments
sh.CurrentDirectory = fso.GetParentFolderName(item)
'working directory is now the parent folder of the current item
'...
Next
If you need the working directory to be the parent directory of the VBScript file you can derive that from the ScriptFullName property:
Set fso = CreateObject("Scripting.FileSystemObject")
WScript.Echo fso.GetParentFolderName(WScript.ScriptFullName)
If I lookup the file types in the Windows registry, I see the following in their Shell\Open\Command values:
batfile: "%1" %*
cmdfile: "%1" %*
exefile: "%1" %*
VBSFile: "%SystemRoot%\System32\WScript.exe" "%1" %*
This seems to suggest that bat, cmd, exe are treated as executable on their own, maybe for historical reasons, whereas VBS is considered an ordinary script, that is only executable because its extension is registered with some executable to be called to interpret it. Pretty much the same as Python or Perl.
[Update] Indeed I proved that a Python script shows exactly the same behaviour as my VBS script: calling it from the command line providing arguments keeps the CWD, dropping a file on it causes the CWD to be C:\Windows\System32. So my question seems to be sort of wrong, but finally it helped people to point me into the right direction for further research...
c:\windows\system32\CScript.exe or c:\windows\system32\Wscript.exe are the programs that run vbscript. As you can see they are in system32.
Windows uses ShellExecuteEx to start programs - see it's rules at MSDN: ShellExecuteEx function (Windows)
ShellExecuteEx uses CreateProcess (CreateProcessEx) to actually start a program. CreateProcess function (Windows)
Edit
CMD doesn't use the registry for it's own stuff. Those registry entries are for programs other than CMD.
CMD main goal is to be MS Dos 5 compatible while enhancing it, it will correctly run most DOS batch files. It was written by IBM engineers working on OS/2 NOT Windows.
Edit 2
The core of your problem is that you are attempting to write programs as if you are a user typing to operate a computer.
As a programmer you don't make assumptions. The easiest way to not take assumptions is to specify full paths to what you want. Your batch file shouldn't care what the current directory is. EG In CMD there is a current directory per drive for compatibility with MSDos 5 (and programs in a console tend to share them but don't have to). In Windows there is one current directory per program. The default current directory has changed over the years.
The only time you should work with the current directory is if you are writing a batchfile for a user to use. EG If you type dir it does the current directory, a batchfile meant to be a general command should work the same way.
ok...Im a new member here and I can express how jolly I am...back to subject
I made a bat file, lets call it 1.bat and I used iexpress to make it an exe file, lets call it 1.exe.
So, in the batch file I added the command line to add a vbs file ( call it 1.vbs ) which is also included in the exe package (1.bat and 1.vbs are in 1.exe) but it installs 1.bat, so in the command I typed:
copy "1.vbs" "C:\Users\%username%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup"
If I run the bat file it copies the vbs file to start up, but if I make the 1.exe file in iexpress by including 1.bat and 1.vbs and when I click the 1.exe file, it doesnt work, it doesn't copy the vbs file to startup, it says something about too many parameters.
I'm sorry if my post is too long or my question have been posted before, but I couldn't found any thread solves my issues, if there is, i'd be glad to be enlightened.
Thanks.
Never use "Batch to EXE" converter, they often do not work as expected. Simply use the batch script.
Just a note, this file actually only acts as a wrapper for your script, and the script itself actually gets executed in a temp folder created on execution (and deleted afterwards), so make sure you don't use any relative paths.
source
When running a batch file in IExpress, you need to call it like:
cmd /c 1.bat
If you don’t, variables like %username%, long file names, etc, will likely not work.
I suspect you are using short file names. Put in your bat dir then pause and you'll see it's 1~1.vbs or similar.
I was trying to make a batch file that compresses a specific folder (using winrar) to a specific location (not the same as the folder location), password (that I can choose myself) protects it AND does all of that without a cmd screen popping up.
I have very little knowledge of programming and managed to get some things working, but not all at the same time and in the same batch file.
Also to rar that file do I need Winrar to be installed on the computer or can I reffer to the rar.exe (copied from the Program Files Windows folder to a different location)?
AFAIK it's not possible to run a a bat file without a visible CMD window without using any additional tools. Here's a link to a post how to run a hidden console: https://superuser.com/questions/62525/run-a-batch-file-in-a-completely-hidden-way
It is possible to use just the rar.exe but I would use 7zip instead. The performance is way better, it's also portable and you have many options in the command line. So your project would contain the bat file itself, the vb script file and the 7z.exe (or rar.exe). If you want, you can even create a single .exe file out of these three by creating a SFX file: http://www.7zsfx.info/en/
Hope I could help you.
I run a batch file as an external tool (by adding it in Tools->External tools) in VS2010 (I've checked the "Use Output Window" option). This batch file performs compilation as in VS command prompt. The project that I'm working on has makefiles for various folders, so I use the mk command to build.
In the batch file, I set up the VS environment and then run the following commands:
cd $directoryWhichContainsFileToBuild
mk
cd main //This directory contains the executable that is to be built
mk
I see the output of the first mk in the Output window but after that it just hangs. I also tried to use an echo after the first mk but even that doesn't get printed in the output window (the ones before it can be seen).
Somewhere I read that there is an issue with VS 2010 output window where it hangs after showing some output, although I couldn't really be sure that that is what's the issue here.
Do I need to enable some other VS setting? Has anybody else encountered this issue?
Thanks.
Update: I unchecked the "Use Output Window" and "Close on exit" option, and I see an extra statement: "Press any key to continue". On doing that however, their is no further processing of the batch file.
Update2: Got it to work by prefixing mk with "call".
Thanks all who tried.
It is always good in batch files to specify executables with full path and file extension instead of just the file name. This avoids often lots of problems.
Here was just mk used instead of mk.bat. Therefore on every compile the command line processor cmd.exe searches for mk.* and then checks if any of the found files have an extension listed in environment variable PATHEXT. The order of file extensions separated by a semicolon in PATHEXT defines the order of execution in case of a directory contains multiple mk.* files.
If a command being specified in a batch file not being an internal command of cmd.exe without path, command line processor searches first for a file with given name in current working directory. This is often one more cause of error. What is the current working directory on execution of the batch file?
Next if no file to execute can be found in current working directory, the command line processor searches in all folders being listed in environment variable PATH separated by semicolons.
So specifying in batch files edited only rarely an external application or another batch file with full path, file name and file extension, in double quotes if necessary because of 1 or more spaces in path or file name, helps command line processor to more quickly execute that application or batch file and avoids problems because of executable not found (unknown command).
Sure, when typing commands in a command prompt window, nobody wants to enter the executables with full path, name and extension. But for batch files it is always good to be not lazy and type files to be executed with full path and extension.
TripeHound has given already the explanation why the observed behavior occurred here.
If a batch file is executed from another batch file without using command call, the command line processor continues batch execution in the other batch file and does never come back. In a C/C++ program this is like using goto with the difference that parameters can be passed to the batch file containing the further commands to be executed next.
But running from within a batch file another batch file with call results in continuation of execution below the line calling the other batch file once the other batch file reaches end, except command exit is used in the called batch file without parameter /B.
So the solution here is using:
cd /D "Directory\Which\Contains\File\To\Build"
call "Path\Containing\Batch\File\To\Build\mk.bat"
rem With mk.bat not changing current working directory change working
rem directory to the directory containing the executable to be built.
cd main
call "Path\Containing\Batch\File\To\Build\mk.bat"
BTW: exit exits command processor, exit /B exits just current batch file. I'll give you three guesses why the parameter is B and not a different letter. Yes, B is the first letter of batch.
Writing as a separate answer instead of an update in the question itself as many readers see the header and skim to the answer: got it to work by prefixing mk with "call". (#TripleHound has also posted the conceptual reason for it in the comment above.)
I would like to know what are the approaches that you use to manage the executables in your system. For example I have almost everything accessible through the command line, but now I come to the limit of the path string, so i can't add any more dir.
So what do you recommend?
A long time ago, I tried to use softLinks of the executables in a Dir that belonged to the path, but that approach didn't work.
Throw the "executable only" to a known Dir,has the problems that almost any application require a set of files, so this also is bad.
Throw the executable and all his files to a known Dir, mmm this will work, but the possibility to get a conflict in the name of the files is very very high.
Create a HardLink? i don't know. What do you think?
This will parse your %PATH% environment variable and convert each directory to its shortname equivalent and then piece it all back together:
#echo off
SET MyPath=%PATH%
echo %MyPath%
echo --
setlocal EnableDelayedExpansion
SET TempPath="%MyPath:;=";"%"
SET var=
FOR %%a IN (%TempPath%) DO (
IF exist %%~sa (
SET "var=!var!;%%~sa"
) ELSE (
echo %%a does not exist
)
)
echo --
echo !var:~1!
Take the output and update the PATH variable in environment variables.
One way I can think of is to use other environment variables to store partial paths; for example, if you have
C:\this_is_a\long_path\that_appears\in_multiple_places\subdir1;
C:\this_is_a\long_path\that_appears\in_multiple_places\subdir2;
then you can create a new environment variable such as
SET P1=C:\this_is_a\long_path\that_appears\in_multiple_places
after which your original paths become
%P1%\subdir1;
%P1%\subdir2;
EDIT: Another option is to create a bin directory that holds .bat files that point to the appropriate .exe files.
EDIT 2: Ben Voigt's comment to another answer mentions that using other environment variables as suggested might not reduce the length of %PATH% because they would be expanded prior to being stored. This may be true and I have not tested for it. Another option though is to use 8dot3 forms for longer directory names, for example C:\Program Files is typically equivalent to C:\PROGRA~1. You can use dir /x to see the shorter names.
EDIT 3: This simple test leads me to believe Ben Voigt is right.
set test1=hello
set test2=%test1%hello
set test1=bye
echo %test2%
At the end of this, you see output hellohello rather than byehello.
EDIT 4: In case you decide to use batch files to eliminate certain paths from %PATH%, you might be concerned about how to pass on arguments from your batch file to your executable such that the process is transparent (i.e., you won't notice any difference between calling the batch file and calling the executable). I don't have a whole lot of experience writing batch files, but this seems to work fine.
#echo off
rem This batch file points to an executable of the same name
rem that is located in another directory. Specify the directory
rem here:
set actualdir=c:\this_is\an_example_path
rem You do not need to change anything that follows.
set actualfile=%0
set args=%1
:beginloop
if "%1" == "" goto endloop
shift
set args=%args% %1
goto beginloop
:endloop
%actualdir%\%actualfile% %args%
As a general rule, you should be careful about running batch files from the internet, since you can do all sorts of things with batch files such as formatting your hard drive. If you don't trust the code above (which I wrote), you can test it by replacing the line
%actualdir%\%actualfile% %args%
with
echo %actualdir%\%actualfile% %args%
Ideally you should know exactly what every line does before you run it.
if you are using windows vista or higher, you can make a symbolic link to the folder. for example:
mklink /d C:\pf "C:\Program Files"
would make a link so c:\pf would be your program files folder. I shaved off 300 characters from my path by using this trick.
In case anyone's interested...
I find I never really need all those paths at once, so I create a bunch of "initialization" batch files which modify the path accordingly.
For example, if I wanted to do some C++ development in Eclipse, I would do:
> initmingw
> initeclipse
> eclipse
This is also handy for avoiding conflicts between executables with the same name (such as the C++ and D compilers, which both have a make.exe).
My batch files typically look like this:
#echo off
set PATH=C:\Path\To\My\Stuff1;%PATH%
set PATH=C:\Path\To\My\Stuff2;%PATH%
I find this approach relatively clean and have yet to run into any problems with it.
I generally don't have to worry about this (I haven't run into a path size limit - I don't even know what that is on modern Windows systems), but here's what I might do to avoid putting a program's directory in the path:
most command line utilities get thrown into a c:\util directory that's on the path
otherwise, I'll add a simple cmd/batch file to the c:\util directory that looks something like:
#"c:\program files\whereever\foo.exe" %*
which essentially creates an alias for the command. It's not necessarily perfect. Some programs really insist on being in the path (that's pretty rare nowadays), and other programs that try to invoke it might not find it properly. But for most uses it works well.
But generally, I haven't had to worry about avoiding adding directories to the path.
Another idea: Use DIR /X to determine the short names generated for non-8dot3 file
names. Then use these in your %PATH%.
For example, 'C:\Program Files' becomes 'C:\PROGRA~1'.
USe the App Path registry key instead of the path variable for application-specific paths:
http://msdn.microsoft.com/en-us/library/windows/desktop/ee872121(v=vs.85).aspx
I wrote and use on a every-time basis a standard stream (stdin/stderr/stdout) & exit code PROXY program (called dispatcher https://github.com/131/dispatcher)
All CLI program i use (node, php, python, git, svn, rsync, plink ...) i'm using are actually the same exe file (around 10kb, that i just name differently), that i put in the same directory. A dummy static clear text file do the "proxy file name to real exe mapping".
Dispatcher use low level Process management win32 API to be absolutly transparent.
Using this software, i only do have ONE additionnal directory set in my PATH for all programs i might use.
Creating a folder c:\bin adding to your path and hardlinking like you said could shorten the string. Maybe add a variable pf to system vars with value c:\Program Files then replace c:\Program Files with %pf% in path.
Edit:
Create a virtual drive.
subst p: "c:\program files"
I follow these steps to make the entries manageable:
Created different users for different combination of software packages usage.
Example: (a) Created a user web for making available all the web development software; (b) Created a user database for making available all the database and data warehousing software packages. Remember some software may create more than one entry. Or sometime I break this into oracle specific and MSSQL specific and oracle specific users. I put MySQL/PostgreSQL, tomcat, wamp, xamp all into the user account webr.
If possible install common packages like office, photoshop, .. as system specific available for all users and special packages as user specific. Of course I had to log into different users and install them. Not all software may provide this option. If "install for this user only" option is not available, install it for the whole system.
I avoid installing programs in to the folder Program File (x86) or in to Program File. I always install into the base directory. For example MySQL 64 bit goes into "C:\mysql64" and MySQL 32 bit goes into "C:\mysql" folder. I always assume adding a suffix 64 only for 64bit software. If no suffix, then it is a 32 bit. I follow the same thing to Java and others. This way my path will be shorter, not including "C:\Program File (x86)". For some software the configuration file may need to be edited to show where exactly the .exe file is. Only program that demands to be installed into "C:\Program File (x86)" will be installed into that folder. Always I remember to shorten the names. I avoid version number like tomcat/release/version-2.5.0.3 such details. If I need to the know version, I create a file by name version and put it into the tomcat folder. In general shorten the link as much as possible.
Include any batch to replace abbreviated link to the path, if all the above steps passed the Windows limit.
Then Log into usage specific (mobile application, or database/data warehousing or web-development.. ..) user and do the relevant tasks.
You can also create virtual windows within windows. As long as you have one licensed OS copy, creating multiple virtual windows with same key is possible. You can put packages specific for a particular task in that machine. You have to launch separate VM each time. Some memory intensive packages like 3D animation movie makers all should be put into the main machine, not into VM as VM will have only a part of the RAM available for its use. It is a pain to boot each VM though.
The solutions above only work if you can trim down your path. In my case, that wasn't really an option, and it was a hassle to have to run a script every time I opened a command prompt. So I wrote a simple script that runs automatically when opening the command prompt, and appends the contents of a text file to your path.
There are also some contexts where having this script run breaks things (say, in a github or cygwin shell), so I also added a file that contains a list of paths that, if the command prompt is started in them, the path variable isn't changed via the startup script that normally updates the path.
#echo off
:: Modify these to the actual paths of these two files
set dontSetupFile=C:\Users\Yams\Dontsetup.txt
set pathFile=C:\Users\Yams\Path.txt
:: Retrieve the current path (for determining whether or not we should append to our path)
set curDir=%cd%
:: Be done if the current path is listed in the dontSetupFile
SetLocal EnableDelayedExpansion
for /F "delims=" %%i in (%dontSetupFile%) do (
if "%%i"=="%curDir%" GOTO AllDone
)
:: Append the pathFile to our current PATH
set pathAppend=
for /F "delims=" %%i in (%pathFile%) do (set pathAppend=!pathAppend!%%i)
set PATH=%PATH%;%pathAppend%
:: The only way to actually modify a command prompt's path via a batch file is by starting
:: up another command prompt window. So we will do this, however, if this script is
:: automatically called on startup of any command prompt window, it will infinately
:: recurse and bad things will happen.
:: If we already ran, we are done
if "%yams%"=="onion" GOTO AllDone
:: Otherwise, flag that we just ran, and then start up a new command prompt window
:: with this flag set
set yams=onion
cmd \K set PATH=%PATH%;
:: When that command prompt exits, it will load back up this command prompt window, and
:: then the user will need to exit out of this as well. This causes this window to
:: automatically exit once the cmd it just spawned is closed.
exit()
:: Path is set up, we are done!
:AllDone
#echo on
And Path.txt will look something like
C:\Program Files (x86)\Google\google_appengine;
C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;
C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;
C:\Program Files\Microsoft SQL Server\110\Tools\Binn;
C:\Program Files\Microsoft DNX\Dnvm;
C:\Program Files (x86)\Windows Kits\8.0\Windows Performance Toolkit;
While Dontsetup.txt will look something like

Didn't try it, but will splitting PATH in parts work and joining them in final variable work?
Example initially let's say you have something like
PATH={LONGPATH1};{LONGPATH2};....{2048th char}....{LONGPATH_N-1};{LONGPATH_N}
Instead you create:
_PATH1 = {LONGPATH1};{LONGPATH2};....{2048 char}
_PATH2 = {2049th char}...{LONGPATH_N-1};{LONGPATH_N}
rem // may be more parts
PATH = %_PATH1%;%_PATH2%
