Win 7 64 Bit Application Error

Experts,

I`m using C# .NET 3.5 Visual Studio 2008.

I`m in the process of porting over my development to a 64 bit OS from a 32 bit OS. I`m getting an error which says "BadImageFormat Exception was unhandled : is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)"

I tried changing the target to X64 and I still get the same errro.

Also, I`m using DirectX libraries. Do you think I`m getting the error because these libraries could be 32 bit?

Any help would be greatly appreciated.

32 bit applications/DLLs have no problem running in 64 bit systems as long as everything runs as 32 bit. Have you tried compiling your exe as 32bit only? I suspect your exe is 64bit and there is some DLL it is using which is 32bit.

Initially everything was set to be 32 Bit. The only dll that is not a 32 bit a hardware based protection key.

So now, I disabled the 64 bit dll and I get a new error

DLL 'C:\SP212\CP2012\CP2012\bin\x86\Debug\Microsoft.DirectX.dll' is attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang.
