Yep, sounds like visual studio isn't running as a true administrator. If you are running with user account control turned on, you will likely want to start VS by right clicking and selecting "Run As Administrator". The other option would be to work through the access issues by opening up the SF folder and registry permissions, but that will likely take some trial and error depending on where the access is getting blocked.I typically turn UAC off on my Dev machines, but whether or not that is a good idea is a matter of opinion (loosing some security in the name of convenience.) With UAC on, even an administrator account isn't really an administrator, and can cause some security headaches here and there.
