Fixing comctl32.dll WIN32Exception

A C# project was recently upgraded from .NET 3.5 to .NET 4.0.
The program worked fine, except on a Windows 8 Pro x64 machine where this error was given:

Win32Exception: Cannot load the “comctl32.dll” DLL into memory.

The solution that worked for us (after a long search) was removing CorFlags to set the application to 32-bits mode. When a new build was created without CorFlags and setting Visual Studio to build the project to x86 instead of x64 solved the problem.

It looks like CorFlags is not reliable…
