Visual C # 2010 MSVCR100.dll is missing when opening a project

Question

I installed Visual C # 2010 Beta 2, and I get this error every time I open a project:

'This application failed to start because MSVCR100.dll was not found. Reinstalling the application may fix the problem. "

I deleted every VC, .NET framework, C # runtime on this computer. Then reinstalled Visual C # 2010, and the installation went smoothly. Then I launched Microsoft Update. Another problem when opening a project. The project was created with VC # 2008.

I am using the 64-bit version of Windows 7.

Any idea how to fix this? I could find people with the same problem when trying to uninstall VS2010 and use the previous version.

Answer 1

After installing Visual Studio Express 2010 Beta 2, I also received the missing msvcr100.dll file. I never got this problem in Windows XP x86, it only happened to me in Win7 x64.

My solution was simple: put / copy the DLL into the System32 folder. I found a local copy of the DLL in the SysWOW64 folder. Therefore, the following command:

copy %windir%\SysWOW64\msvcr100.dll %windir%\System32\msvcr100.dll

Answer 2

I was curious why MSVCR100.dll did not get into System32 or SysWOW64. The MSDN article [1] does not say this explicitly, and no one else has explained it here, but the reason seems pretty clear:

, Visual ++ #, MSVR *.dll. MSVCR100.dll , , ( ), , , , - , , , , .

, "Program Files/Application-Name" (, , EXE , , , Uninstall.exe). , , EXE ( EXE ); DLL ( EXE , DLL), [2].

, DLL: Visual # 2010 , MSVC.

(: MSVCR100.dll - C ( CRL) Visual ++. "R" "", - Micro Soft Visual C. .exe , , (), , , . DLL (++ - ) . DLL , , , , .)
