Cannot run 3DMark11 - Ouch! Something has go wrong

[encode]

Could not load file or assembly 'EvaDotNet.DirectX.dll' or one of its dependencies. is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)

I tried all things suggested in 3DMark11 Support/Forum. Reinstalled .Net4, DirectX, Installed all Windows Updates, etc. etc.

Do you have all Windows updates installed?

Beyond that... there is something fishy with the OS.

You could try running the 32bit binary of 3DMark 11 (you may have to reinstall, use custom and specifically add the 32bit version). If that works, it confirms that the operating system files related to 64bit Dot.Net are somehow corrupt.

All updates are installed. 32-bit version works! Many times installed&reinstalled Dot.Net. I guess I need reinstall the Windows...
