Since FxCop 10.0 is distributed as part of Windows 7 SDK, you have to do some download and extractions to install it on servers which are not running Windows 7.
I followed instructions on
http://ruthlesslyhelpful.net/2011/06/09/liberate-fxcop-10-0/ to extract the setup file and uploaded it to this project for easy access.
There has not been any modification to the original binary file. You can check the file size, version # and the signature of the assembly to verify its authenticity.
