I am using Poco library and when running my program on other machines which don't have VS2005 installed, I have to install "Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package ATL Security Update", otherwise the the program will give error when launching.
What is this redistributable package for? Is there any way to avoid installing this but still let my program running well?
Also, there're so many vcredist_x86.exe out there. How can I know which one is necessary or not when getting error? Thanks.
This package contains the msvc*.dll files that your program depends on.
These files contain functions that (almost) every app compiled with VC++ uses for internal memory management, etc.
If you don't want this dependency, then you need to statically link to the runtime library. (Which according to Microsoft is not recommended.)

I have a fairly large project in Visual Studio 2010
I can build the project in both Debug and Release mode, copy the generated exe file along with a custom dll I need for a function in the program to another computer, and the exe file works without any problems
I am trying to make an installer for this project in Visual Studio 2010, following the instructions here: https://www.technical-recipes.com/2011/how-to-create-an-installer-in-microsoft-visual-studio/
I do not get any errors while building the installer, and I get a setup.exe and an msi file as a result, but if I install my program in another computer (not by development machine), when I try to run my program after installation I get a missing api-ms-win-crt-runtime-l1-1-0.dll error
How do I debug this problem? Since I can simply copy my Release or Debug build to the computer and make it work, doesn't it mean all the dll files my program is dependent on already exists in the other computer? And if this already works, why isn't the installer version working? How do I make sure that everything I need for this program is included in the installer?
My project in MFC dialog based and uses one third party library, for which I have both .lib and .dll file available. I need to do this in Visual Studio 2010. My development machine is Windows 10 64 bit Home edition version 1909. The installer I currently create installs my program in Program Files (x86) folder.
Static Linking MFC: It appears this issue was solved by making sure to statically link to MFC libraries. In the VC++ project: enable the setting: "include MFC in a static library". This enables static linking of MFC components, eliminating the dependency on shared dlls.
This is a common "missing runtime error" - there are generic check lists below which include this as one source for application launch problems.
Warning: Generally static linking should be avoided in order to benefit from security updates to shared dll files via other update mechanisms.
Short Version: In Visual Studio Installer Projects, check if the Visual C++ Runtime is available in the Prerequisites list.
See this answer, here is a quick screen shot:
Tools: If your project is large you might want to consider another MSI tool. There are many limitations with Visual Studio Installer Projects.
Merge Modules: There are merge modules to install the Visual Studio C++ Runtime, but it is recommended to use the setup.exe for these reasons.
Visual C/C++ Runtime: You are probably just missing the Visual Studio C/C++ Runtime. It needs to be deployed with your application, it is not on there by default (unless you link statically, in which case it should not be needed). Skim this list quickly for other ideas.
You can download the VC++ redistributables at ("The latest supported Visual C++ downloads"):

Installing VC++ Runtime with merge modules
I'm writing a simple C++ application in Visual Studio. It also has a setup project.
It works well on my development machine, but when I'm installing this application on user's machine it requires Visual C++ Redistributable Package. I'm wondering why does my application require C++ Redistributable? Standard C++ runtime library is shipped with Windows, isn't it?
The only version of the C runtime library which is shipped by Microsoft with most of 32 bit Windows versions is msvcrt.dll. This library provides a typical set of library functions required by C and C++ programs. These include string manipulation, memory allocation, C-style input/output calls, etc.
Visual Studio 6.0's compiler links against this library, so if you are developing in VS 6.0 you shouldn't encounter any problems on most users' machines.
However, if you are developing in VS 2005, VS 2008, VS 2010, VS 2012, VS 2013 or VS 2015, you have to distribute additional C runtime libraries along with your application. This is because their compilers link against msvcrt80.dll, msvcrt90.dll, msvcrt100.dll, msvcrt110.dll, msvcrt120.dll and msvcrt140.dll respectively, which are not shipped with Windows.
Solutions:
Possible solution is to link statically with runtime library, but it may cause a lot of problems in case you have both .exe and .dll in your application. Don't do that.
To be more specific, I'll allow myself to quote a part of this answer:
Using /MT is risky if you create DLLs as well as an EXE. You'll end up
with multiple copies of the CRT in your program. This was especially a
problem with earlier versions of VS where each CRT would get its own
heap, not so much with VS2012. But you can still have ugly runtime
problems when you have more than one "errno" variable for example.
Using /MD is highly recommended to avoid such lossage.
Another possible solution is to require an appropriate Microsoft Visual C++ Redistributable package to be installed on the user's machine.
It may be done by specifying this requirement in prerequisites property in your setup project.
Also, you can distribute the runtime dll by including in your setup project the appropriate "merge module". In this case don't forget to add the appropriate "policy merge module" to avoid errors caused by incorrect runtime version.
Finally, you can just put required DLLs in the same folder in which your application is installed.
Further reading:
"Redistributing Visual C++ Files" - Official MSDN documentation
Even though some comments said that «link statically with runtime library, but it may cause a lot of problems when you have both .exe and .dll in your application.» this is NOT TRUE. First we DON'T statically link DLLs! We statically link OBJs and LIBs. LIBs are static libraries; DLLs are dynamic libraries, and you may choose to use LIBs (static) or DLLs (dynamic). It's entirely up to you to choose. The ONLY drawback (for the DLL fans) is that if you want to update one library, you need to compile and link again. I personally deploy ALL my software static linked and because of that I earn the bonus of don't even need installers. The software I develop is 100% portable (a feature that in the pre-installer era was general procedure), and the final user is free to simple COPY from one folder to another or even from the hard drive to flash drive (or vice-versa). The error message «DLL not found.» simply doesn't exist ... NEVER.
Some folks think of statically linking as toy software: WRONG! I can write a full featured application that connects to a DBMS (Oracle, SQL Server, ...) or any other kind of application.
I know this has been asked in other places and answered, but I'm having issues with MS Visual Studio 2010. I've developed a C++ executable but if I run the Release version on a machine that doesn't have the VC++ runtime library (ie, msvcr100d.dll), I get the "program cannot start because msvcr100d.dll is missing from your computer" error.
This is weird for two reasons:
Why is it trying to link with the debug version of the redistributable?
I tried applying this fix, setting the runtime library setting to /MT instead of /MD (multi-threaded DLL), but that only made the problem worse (if I manually copied msvcr100d.dll, it then said it couldn't find msvcp110.dll).
How can I package the runtime library with my executable so that I can run it on machines that don't have MS VC 2010 or the redistributable installed?
I know it's considered a security risk to include a copy of the DLL since it won't ever be updated, but my goal is just to send this executable to a few friends in the short term.
You definitely should not need the debug version of the CRT if you're compiling in "release" mode. You can tell they're the debug versions of the DLLs because they end with a d.
More to the point, the debug version is not redistributable, so it's not as simple as "packaging" it with your executable, or zipping up those DLLs.
Check to be sure that you're compiling all components of your application in "release" mode, and that you're linking the correct version of the CRT and any other libraries you use (e.g., MFC, ATL, etc.).
You will, of course, require msvcr100.dll (note the absence of the d suffix) and some others if they are not already installed. Direct your friends to download the Visual C++ 2010 Redistributable (or x64), or include this with your application automatically by building an installer.
For me the problem appeared in this situation:
I installed VS2012 and did not need VS2010 anymore.
I wanted to get my computer clean and also removed the VS2010 runtime executables, thinking that no other program would use it.
Then I wanted to test my DLL by attaching it to a program (let's call it program X).
I got the same error message.
I thought that I did something wrong when compiling the DLL.
However, the real problem was that I attached the DLL to program X, and program X was compiled in VS2010 with debug info. That is why the error was thrown.
I recompiled program X in VS2012, and the error was gone.
This problem explained in MSDN Library and as I understand installing Microsoft's Redistributable Package can help.
But sometimes the following solution can be used (as developer's side solution):
In your Visual Studio, open Project properties -> Configuration properties -> C/C++ -> Code generation
and change option Runtime Library to /MT instead of /MD
Usually the application that misses the .dll indicates what version you need – if one does not work, simply download the Microsoft visual C++ 2010 x86 or x64
from this link:
For 32 bit OS:Here
For 64 bit OS:Here
I got the same error.
I was refering a VS2010 DLL in a VS2012 project.
Just recompiled the DLL on VS2012 and now everything is fine.
Debug version of the vc++ library dlls are NOT meant to be redistributed!
Debug versions of an application are not redistributable, and debug
versions of the Visual C++ library DLLs are not redistributable. You
may deploy debug versions of applications and Visual C++ DLLs only to
your other computers, for the sole purpose of debugging and testing
the applications on a computer that does not have Visual Studio
installed. For more information, see Redistributing Visual C++ Files.

I work on a machine with win 7 32bit on visual studio 2010.
I tried to run in release mode a code that work fine on other computer(win7 64bit), and the following message came up:
The program can't start because msvcp80.dll is missing...
I tried looking up at threads dealing with this problem. tried to install diffrent Redistributable runtime versions. tried to copy those files(msvcp80.dll,msvcm80.dll, msvcr80.dll) to the project dir. and some diffrent things I don't even realised what I'm doing.
maybe some other ideas?
OK
thanks for your answers.
before i started the project i confirm all the build dll are 32bit.
I work on a 'opencv' project and narrow the problem to this one: the only problem occurred on opencv_imgproc230 lib function (like cvtColor, GaussianBlur)' what cause me to check with the program above(the_mandrill's link) the includes at this dll. it's include(or point I guess) for msvcp100.dll what seems reasonable because i work on VS10 enviroment.but even though it's screams for msvcp80.dll what belongs to VS80 I think.
by the way, when i manually include (msvcp80.dll,msvcm80.dll, msvcr80.dll) it's screams:
"R6034 An application has made an attempt to load the c runtime library incorrectly..."
It's seems that it's need to tell him to work with the VS10 version(for this dll's/runtime library)
Install Dependency Walker and run in 'Profile' mode (f7) which will show you the dlls it's looking for and failing to find.
This just means that you link agains MSVC C runtime dynamically.
So you have to install the so called redist package.
msvcp80.dll -> VC 8 -> VS 2005
X86 – http://www.microsoft.com/downloads/details.aspx?FamilyId=32BC1BEE-A3F9-4C13-9C99-220B62A191EE&displaylang=en
X64 - http://www.microsoft.com/downloads/details.aspx?FamilyId=90548130-4468-4BBC-9673-D6ACABD5D13B&displaylang=en
The dlls where installed to a central place by the redisrt package and should be resolvable after installation.
Can you check to see if your dlls are 32bit ? Maybe you have the 64 bit versions.
See How can I test a Windows DLL file to determine if it is 32 bit or 64 bit?.
See this question.
You mentioned that you've installed the VC8 redistribute packages, but you may have missed the "correct" one.
You probably want: Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package MFC Security Update
I'm using the Visual Studio Setup project. If I go to the properties of the Setup project, it lets me choose which pre-reqs are required, at which point I choose the C++ Redistributable.
On some systems, this works fine - but recently my users are reporting that the install failed because "A newer version of Microsoft Visual C++ 2010 Redistributable has been detected on the machine."
What's the proper way to do this? Is Visual Studio's detection fouled up somehow and unable to detect C++?
Yuck, this is ugly. I was wondering what would happen after Microsoft gave up on the side-by-side install of the runtime DLLs for VS2010. Seems clear, the interwebs are full of this installer error. The biggest victim seems to be Microsoft itself with Streets and Maps failing to install.
I'm not aware of any security patches for it so I have to guess that you haven't updated to SP1 yet. And your customers use a product of a vendor that did. This is a battle that you're always going to lose some day. Do consider taking advantage of the app-local deployment for the DLLs, copying them in the same directory as your main EXE. Simply copy them from the vc/redist directory before putting the setup package together, no need to tick the prerequisite. You'll need:
msvcr100.dll and msvcp100.dll for the regular CRT
atl100.dll if you use ATL
mfc100.dll, mfc100u.dll, mfcm100.dll, mfc100u.dll if you use MFC (u = Unicode, m = managed)
mfc100xxx.dll where xxx is the 3 letter language code if you use MFC on a non-English machine
vcomp100.dll if you use OpenMP in your code.
Only disadvantage is that they won't get updated if there's a security patch. That could be an advantage too, depending on what color glasses you wear. If you're uncomfortable about it then keeping the machine that creates the setup package updated, including enabling Windows Update, is an important requirement.
The default Visual C++ 2010 Redistributable uses a Product Code for detection. So Visual C++ 2010 SP1 Redistributable is not detected as installed. This is why the package tries to install it and fails.
A good solution is to create your own custom prerequisite which uses a better detection criteria. Here is an article which may help you:
http://blogs.msdn.com/b/astebner/archive/2010/05/05/10008146.aspx
Visual Studio setup projects do not support custom prerequisite creation. However, it can be done by manually generating the required manifests.
You can find the manifests structure here: http://msdn.microsoft.com/en-us/library/ms229223(VS.80).aspx
These manifests can be generated automatically with the Bootstrapper Manifest Generator tool.
After generating the package manifests, you can add all these files (including the package) in a separate folder in the Visual Studio prerequisites folder, for example:
C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper\Packages\
This way Visual Studio will show the prerequisite in your setup project properties page.
