First of all this is something that needs to be verified, and it worked for my 64bit PC, hopefully will work for yours too.
You need to install two setups microsoft provides, the .Net framework and the Redistributable Package.
Also do not forget to run CR as administrator.
New Edit: Use Windows7 x64 Home Premium not Ultimate!
Here the links.
.NET Framework

Microsoft Visual C++ 2010 Redistributable Package (x64)

Please post your feedbacks, as I said this needs to be verified.
Thanks
