I tried the same code on Windows 7 and it works.
I have no idea what goes wrong.
Any idea?

It looks like your main problem is the inner exception you got:
InnerException: System.IO.FileLoadException
Message=Could not load file or assembly 'System, Version=2.0.5.0, Culture=neutral,
PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes' or one of its dependencies.
The good news is that you should just install the following patch: KB2468871, as suggested here:
