How to get Visual C++ 2012 Update 2 statically linked applications to run on Windows XP

EDIT (June 26, 2013) – Microsoft has released the final version of Visual Studio 2012 Update 3 that completely fixes this issue.  For more information on Update 3, please click here.

EDIT (May 11, 2013) – Microsoft has released an RC of Visual Studio 2012 Update 3 that fixes this issue which is “go live”, meaning if you can’t wait for the final Update 3 and need a Microsoft supported solution immediately, you can use it with production releases.  For more info look here and to download look here. For a solution to use with Update 2, see below.

Due to a regression in Visual C++ 2012 Update 2, applications using ATL will no longer be able to run on XP, even if using built-in XP targeting support.  This is due to a new dependency on InitializeCriticalSectionEx.  Running an app on XP that was built with Visual C++ 2012 Update 2 will give you the following error message:

Entry Point Not Found

The procedure entry point InitializeCriticalSectionEx could not be located in the dynamic link library KERNEL32.dll

To fix this, I’ve published a new version of the xpsupport tool, namely XPSupport for VC11 Update 2 Version 1.02, on my skydrive.  It simply wraps the InitializeCriticalSectionEx function with an XP compatible replacement, using techniques I’ve used in previous blog entries.

To use this solution, simply add build customizations (masm) to your project by right clicking on the project in solution explorer and choosing “build customizations” and check masm (targets, props) on, then add the three files (xpatl.cpp, xpatlwrap.asm, and xpatlwrap64.asm) contained in the zip file named: found here:!153&authkey=!AEAOQJ4-LCqWQiw

Build your app, and now your app will run under XP.

EDIT: despite the title of this blog post, I received reports that this works also for dynamically linked apps (i.e. linking to MFC and the CRT dynamically)

    Thanks for the files; on inspection, these appear to be for 32-bit builds (or at least the asm code does not do anything for 64-bit). Is there a similar thing to do for x64, or am I missing something?

    • tedwvc says:

      You’re right – for XP x64 and Windows Server 2003 x64 I didn’t publish the ASM, but will do so since you asked for it.

      • tedwvc says:

        Hi Greg – I updated the article and uploaded the skydrive with the new version that contains the x64 asm file. Feel free to add all three files to the project since the asm files automatically include/exclude themselves from the appropriate builds at build time.

  3. Greg Smith says:

    Many thanks. I will try this tomorrow and let you know how it goes. I’m using dynamic links for MFC but hit the problem due to using the CImage library, which links to some of the ATL static libs.

    Lifesaver! Microsoft may not have completely forgot their older operating systems but they should have a few VMs running to test their updates.

    Great work Ted, saved me a lot of headaches!

  5. Greg Smith says:

    I have now checked this for an MFC DLL app that used ATL via CImage and it works in both x64 and x86 versions. Thank you.

    On a separate issue, while perusing your blog via Chrome on an Android Tablet, the Follow pop-up obscures a large proportion of the screen and doesn;t seem to want to go away if you do not choose to Follow…

    • tedwvc says:

      Hi Greg, thanks for confirming this works with dynamically linked apps also.

      I turned off the “follow” button from the page (but it only allows me to turn it off for “logged off users”). Hopefully this will solve the problem, thanks for making me aware of it.

  6. Jan Rysavy says:

    Thank you for this fix! I’m getting following exception: Run-Time Check Failure #1 – A cast to a smaller data type has caused a loss of data. If this was intentional, you should mask the source of the cast with the appropriate bitmask. For example: char c = (i & 0xFF);
    Changing the code in this way will not affect the quality of the resulting optimized.

    Fix: use DWORD instead of BYTE cast:
    if ((DWORD)::GetVersion() >= 6) { // Vista or higher

    another option is disabling runtime checks:

    #pragma runtime_checks(“”, off)

    #pragma runtime_checks(“”, restore)

  7. Thank you, Thank you, Thank you!

  8. Michael McCarthy says:

    Thank you you saved me! I upgraded to VS 2012 and would have had to roll back to 2010 without this fix.

  9. J.S. says:

    Is this not the job of those at MS? How can it break, if not on purpose?. Should you better leave it alone?

  10. Sascha says:

    Just for reference, here ist the direct link to update 1 (all official MS links now redirect to update 2):

    Since I don’t like hacks and have no requirement for update 2, I will simply skip it. There is already update 3 CTP available, so it shouldn’t take long till update 3 gets released officially.

  11. devsh says:

    Thank you.
    Since the development period given to us was short, it was saved very much.

  12. Filippo Scarponi says:

    I had the same issue and the workaround saved also my life. I add my compliments and thanks to the others’ : I avoided a very big headache..
    I just add a note that may be useful for people not used to embed MASM files in the solution (like me :) ) : after adding the .asm files to the project, I had to right-click on them and specify that they were microsoft macro assembler files, in order to have a good result : by default, Visualstudio was excluding them from the build, so there was no good result even if, apparently, the solution was building without errors.

    Thank you again very much !!

    • tedwvc says:

      Thanks, it’s great to hear the solution helped. I’ve had the same issue as you had, it just ignored the asm file, then I finally realized, it was only if I didn’t do the step of right clicking on the project file (not the solution) and choosing build customizations, and checking “masm (targets, props)” before adding any ASM files. The key was that this step needs to be done BEFORE adding any ASM files to your project. If you add the ASM files before doing the step, then it will ignore your build customizations, and you can do your workaround instead.

  13. Sven says:

    Another workaround is to replace the atlsXXX.lib’s with the lib’s from update 1.

  14. Greg Smith says:

    Just a note to say that I have installed Update 3 RC 1 and it seems to have fixed the XP problems for a build that uses MFC in a DLL and the CImage object, which links to the ATL library. This works in both x86 and x64. Note that there is a new mfc110.dll file.

    Nothing extra seems to have been broken.

    Thanks to Ted for the work-around while we waited…

  15. Amit says:

    Hi Ted,
    I’m encountering this problem (not a valid win32 application when running on XP) for something I’m compiling with VS2012 Update 3. Any way to find out what exactly is the trigger for this?

    • tedwvc says:

      Did you choose the correct platform toolset in project properties? It has to be set to: Visual Studio 2012 – Windows XP (v110_xp)

      Also there is a bug where sometimes in project properties – linker – system – minimum required version is blank and not set properly. It should be set to 5.01 (automatically by setting the platform toolset) but if it is still blank put 5.01 in there.

      • Amit says:

        Hi Ted,
        Thanks for the answer. Meanwhile we were in a tight spot, so we reverted to VS2008 for the components that were exhibiting the issue. We think it’s related to external libraries we’re linking to and for which we don’t know how they were compiled.
        Thanks again.

    Hi, Ted,
    I’ve got Visual C++ 2012 Update 4 but still have the “Entry Point Not Found” error. Could it be something that Update 3 fixed but broken by Update 4? I applied your workaround and it worked for Update 4.

    BTW, I checked both “platform toolset” and “linker – system – minimum required version” in project properties and they all set correctly. But I still have this error unless I apply your workaround.
