COM Executable Crash compiled with VS2012 on Windows 2012

I faced this problem while migrating one of my COM applications from VS2008 to VS2012.

Problem: COM application crashes when compiled with VS2012 on Windows 2012

1. Search for a class like below in your code which inherits from CAfwAtlExeModuleT<>.

class CAsset_Tree_Module : public CAfwAtlExeModuleT< CAsset_Tree_Module >

2. You might see a method similar to the one below in that class (if yes than there is a trap):

HRESULT RegisterClassObjects(DWORD dwClsContext, DWORD dwFlags) throw()
{
    return AtlComModuleRegisterClassObjects(&_AtlComModule, CLSCTX_LOCAL_SERVER, REGCLS_SINGLEUSE);
}

3. As per Microsoft, in Visual Studio 2012, this function cannot be used in applications that execute in the Windows Runtime.

Just change the version of Visual Studio (2010 to 2012) in the above link to see the difference. 

Here is the solution:

Replace this line:

return AtlComModuleRegisterClassObjects(&_AtlComModule, CLSCTX_LOCAL_SERVER, REGCLS_SINGLEUSE);

with this code block:

#if _MSC_VER > 1600
    dwFlags &= ~REGCLS_MULTIPLEUSE;
    dwFlags |= REGCLS_SINGLEUSE;
    return __super::RegisterClassObjects(dwClsContext,dwFlags);

#else
    return AtlComModuleRegisterClassObjects(&_AtlComModule, 
                  CLSCTX_LOCAL_SERVER, REGCLS_SINGLEUSE);
#endif
