How can I call a 64-bit exe from a 32-bit exe in windows 7?
My requirement is I have created a batch file and have converted into exe using iexpress.
This exe works fine when I converted this exe from a 32-bit pc for a 32-bit pc.
And This exe works fine when I converted this exe from a 64-bit pc for a 64-bit pc.
When I tried to run 64bit from 31bit pc it show error Not valid
But I need to include this both for a single installation and call.
How can I do this ?
Excuse me, I think there is a misunderstanding here.
I understand that you have both .exe versions of a same program, one for 32-bit and one for 64-bit. However, you want NOT to execute both versions in every computer, but just the appropriate version for the underlaying OS, isn't it?
This way, you must include both .exe files in the installation files, but copy just one in the computer, so you just need to identify the version of the installing computer:
if exist "%SYSTEMDRIVE%\Program Files (x86)" (
rem The OS is 64 bit
copy D:\program_v64.exe C:\program.exe
) else (
rem The OS is 32 bit
copy D:\program_v32.exe C:\program.exe
)

Which of these files( in setup folder), if execute can install a program on windows 7 ?
1- setup.com
2-setup.ini
3-setup.inf
COM files are executable in Windows. You should be able to run setup.com from the CMD prompt by cding to the directory setup.com is in, and running setup or setup.com.
Keep in mind, COM files cannot be executed on 64-bit versions of Windows, since these editions lack NTVDM, the MS-DOS-emulating subsystem that handles COM file execution. You would instead need to emulate the 32-bit environment using an emulator like DOSBox.
setup.inf can be used to file copy and installation. I cannot remember setup.com installers for Windows programs.

When i executed the command via command propmt to install the driver :
cd C:\Windows\System32
pnputil.exe -i -a "C:\Users\Desktop\Drivers\IPEnabled_001.inf"
It work fine.
But if i execute the command in Installanywhere tool
It showing the error message:
pnputil.exe is not recognized as an internal or external command
So could you please tell why it is showing the error message and how the reslove that error?
Thanks in advance.
Please also suggest the alternate way to install inf driver
pnputil.exe is on 64-bit Windows available only as 64-bit application which means there is %SystemRoot%\System32\pnputil.exe (x64) but no %SystemRoot%\SysWOW64\pnputil.exe (x86).
Which directory becomes current directory on using cd C:\Windows\System32 depends on 64-bit Windows on architecture of the application which started Windows command interpreter cmd.exe. A 64-bit application starts really %SystemRoot%\System32\cmd.exe, but a 32-bit application starts %SystemRoot%\SysWOW64\cmd.exe. The reason is the Windows File System Redirector which redirects any file access to %SystemRoot%\System32 to the directory %SystemRoot%\SysWOW64 on Windows x64 for x86 applications.
It is best to check for existence of this file before executing it for this task running pnputil.exe existing only in directory %SystemRoot%\System32 on any Windows independent on Windows architecture.
if exist %SystemRoot%\System32\pnputil.exe (
set "SystemPath=%SystemRoot%\System32"
) else if exist %SystemRoot%\Sysnative\pnputil.exe (
set "SystemPath=%SystemRoot%\Sysnative"
) else (
echo ERROR: Cannot find pnputil.exe to install the driver.
echo/
pause
goto :EOF
)
%SystemPath%\pnputil.exe -i -a "%USERPROFILE%\Desktop\Drivers\IPEnabled_001.inf"
The first IF condition is true for 32-bit applications on 32-bit Windows and 64-bit applications on 64-bit Windows.
The second IF condition is true for 32-bit applications on 64-bit Windows. Sysnative is a special redirector for x86 applications on Windows x64. Sysnative does not exist for x64 applications. Sysnative is not a directory or a symbolic link or a hard link. So it is not possible to use if exist %SystemRoot%\Sysnative as this condition is never true. It is required to check if a file exists in the redirected directory, for example with if exist %SystemRoot%\Sysnative\* which is only true on running currently 32-bit cmd.exe on 64-bit Windows.
The final ELSE branch is true for example on Windows XP which does not have pnputil.exe at all.
However, it is not recommended to use pnputil.exe to install drivers. Microsoft publishes for free the Driver Package Installer DPInst. There is a 32-bit (dpinst32.exe) and a 64-bit version (dpinst64.exe). Installation of one or more drivers is very easy using the driver package installer.
Let us look on how hardware producing companies which offer also the appropriate drivers like Intel ® install drivers using Driver Package Installer.
There is usually a directory structure in a driver installer package like:
VISTA32
VISTA64
WIN7-x86
WIN7-x64
XPx86
XPx64
Or a directory structure like:
VISTA
x86
x64
WIN7
x86
x64
XP
x86
x64
The directory structure varies from installer package to installer package, but that does not really matter and usually it is quite easy to see which driver files in which directory are for which version of Windows including architecture.
And there are additionally dpinst32.exe and dpinst64.exe being either stored in parent directory of all the subdirectories with the driver files or on just two driver directories directly in the directory containing the driver files.
Let us make the driver installation example very simple and assume there are only two driver files in a package, one for Windows x86 and one for Windows x64.
WIN-32
dpinst32.exe
*.cat
*.dll
*.inf
*.sys
WIN-64
dpinst64.exe
*.cat
*.dll
*.inf
*.sys
The code to install the 32-bit driver(s) in WIN-32 on 32-bit Windows and 64-bit driver(s) in WIN-64 on 64-bit Windows by a simple batch file executed either by 32-bit or 64-bit cmd.exe is very easy.
set "WINARCH=64"
if "%ProgramFiles(x86)%" == "" set "WINARCH=32"
cd WIN-%WINARCH%
dpinst%WINARCH%.exe
The environment variable ProgramFiles(x86) exists only on Windows x64 which makes it very easy to determine the architecture of Windows, see also WOW64 Implementation Details. The architecture of the processor does not really matter because on a PC with an AMD 64-bit (compatible) processor can be installed nevertheless a 32-bit Windows.
dpinst32.exe and dpinst64.exe started without any option simply install all drivers found in current directory.
What happens when I use the environment variable %PROGRAMFILES(x86)% on a Windows OS that is 32bit (ie, older versions of Windows such as Windows XP, Vista)?
I am hoping that it will simply resolve to: C:/Program Files. Will this occur?
According to this the environment variable %PROGRAMFILES(x86)% is only available on 64-bit systems.
However, if you are on a 64-bit system and use %PROGRAMFILES%, the result you get depend on whether the process requesting the environment variable is 32-bit or 64-bit.
So from a 64-bit process on a 64-bit system you would get C:\Program Files, from a 32-bit process on a 64-bit system you would get C:\Program Files (x86), and from a 32-bit process on a 32-bit system you would get C:\Program Files.
If this doesn't help, perhaps you can comment or edit your original question to make it specific what you are trying to do. As it currently stands, the answer to your question is "No".
Keith Hill answered this question here, summary:
${env:ProgramFiles(x86)} is not defined on a 32-bit machine
If you always want to put/get data to/from x86 directory, then you can use this code to determine file paths:
$file = "\file"
if ("${Env:ProgramFiles(x86)}")
{
$fullPath = "${Env:ProgramFiles(x86)}\$file"
}
else
{
$fullPath = "${Env:ProgramFiles}\$file"
}
Since %ProgramFiles(x86)% is not defined on Windows 7 32 bit, here is a workaround I came up with:
SET MyPath="%ProgramFiles(x86)%\MyFolder\MyApplication.exe"
rem workaround for Windows7 32 bit:
IF NOT DEFINED ProgramFiles(x86) SET MyPath="%PROGRAMFILES%\MyFolder\MyApplication.exe"
Use case: I want to call an application from a batch file that is installed:
on Windows 7 32 bit in C:\Program Files\MyFolder\MyApplication.exe
on Windows 7 64 bit in C:\Program Files(x86)\MyFolder\MyApplication.exe
This way %MyPath% always points to the correct path.
If you use %programfiles% on a 32-bit computer/laptop it will open C:\Program Files.
If you use %programfiles% on a 64-bit computer/laptop it will open C:\Program Files.
If you have a 64-bit program installed on a 32-bit computer/laptop, it will be installed in a new folder named Program Files (x64), which is located in the "C" drive. In which case you have to use %programfiles(x64).
If you have a 32-bit program installed on a 64-bit computer/laptop, it will be installed in a new folder named Program Files (x86), which is located in the "C" drive. In which case you have to use %programfiles(x86).
I would like to install my USB device driver [.inf file] using PnPUtil.exe utility on both 32bit and 64bit systems for Windows Vista and Windows 7.
I tested on my machine [Windows 7 32bit] and everything was fine because PnpUtil.exe is located in: C:\Windows\System32\PnPUtil.exe.
But in 64bit Windows 7 the utility is not in this directory.
When I tried installing driver on different Windows 7 - 64bit machine I could found PnPUtil.exe in this location: C:\WIndows\winsxs\amd64_microsoft-windows-pnputil_31bf3856ad364e35_6.1.7600.16385_none_5958b438d6388d15\pnputil.exe
and the test was also fine.
So how can I exactly detect this directory on all platforms?
I noticed the path is dependent on built of Windows version - 6.1.7600.16385 - but how to detect the rest of path?
Or is the path always the same on all 64 bit platforms? And what about Vista?
The location of PnPUtil.exe seen from you installer application depends on the bitness of your installer:
32bit installer on 32bit Windows: %WinDir%\System32
64bit installer on 64bit Windows: %WinDir%\System32
32bit installer on 64bit Windows: %WinDir%\Sysnative (Windows Vista and up)

I recently came across this problem while trying to create an installer for ReplicatorG, which includes the Arduino drivers and some drivers specific to the Makerbot Replicator.
It seemed that there isn't any way to determine the location of PnPutil, and I instead had to acquire Microsoft's DIFx and use their redistributable DPinst.
There were a couple of strange things about DPinst that made it difficult to use. The first is that it didn't seem to run properly if it was located in a directory tree with spaces in the path. Who knows why. The second was that, because the Arduino drivers are unsigned, it needed to be run in legacy mode to keep from popping up a big, red dialog warning the user. To run it in legacy mode you use the /lm flag, but the flag must be lowercase. Again, it's unclear why.
In the end, I had the installer copy dpinst and each of the drivers to a folder in the temporary directory and then run dpinst. It pops up a nice little wizard and tells the user which drivers were installed.
From C:\WIndows\winsxs\
dir /s PnPUtil.*
will scan subdirectories
What is the "correct" way for a 32-bit application to find the "Program Files" folder on 64-bit Windows? For example, I am running a 32-bit application with a VBScript engine, and want to launch 64-bit Excel (using ShellExec, or similar). In the 32-bit world, I would check the environment variable "ProgramFiles" to get the base folder. My understanding is that as a 32-bit app on a 64-bit Windows, that environment variable will point to the 32-bit program files folder - eg: C:\Program Files(x86). But my 64-bit Excel will be under C:\Program Files.
I want to avoid hard-coding a reference to "c:\program files".
You can check the environment variable "ProgramW6432". It should exist and point to Program Files, without the x86, when running a 32bit application on a 64bit Windows.

Depending on the version of windows, you should be using the known folders apis.

Specifically you can use FOLDERID_ProgramFilesX64 in conjunction with SHGetKnownFolderPath.
