Processor error while installing

Jul 30, 2010 at 7:04 AM

I try to run the setup file of virtual desk beta(2) but i am getting a processor error saying "this installation package is not supported by this processor type. Contact your product vendor".  How to resolve this problem?

when i try to open the source code it is asking for username and password of Team Foundation Server.  Pls provide me with the username and password to proceed.
