Corflags.exe - correcting problems running 32-bit .NET apps in App-V

Corflags.exe is a tool in the the .NET SDK which can specifically apply 32-bit identification headers to existing 32-bit .NET exe assemblies.  If the 32-bit id flags are not present it can prevent 64-bit Windows from properly launching 32-bit programs.

Sometimes a 32-bit application will launch correctly when locally installed on a 64-bit copy of Windows, however it may exhibit errors when it is sequenced and running in an App-V bubble.
