OK.. I installed.. however the CD key provided when I dlownloaded the program stated invalid.. so I went back and got a new key.. In order for your Key to work.. you have to Install Windows 7 first, launch the OS without inputting a key, go back to MS web site and then request key, and enter requested key as soon as it is displayed on the web page.. make sure you get a full key because the 15 character key is invalid.. follow getting a key instructions exactly.. I did this and my system is now fully activated..
Only problem I ran into Upgrading my system.. I had to reinstall device drivers.. some survived migration, but my system audio driver didn't make the transition.. so to be safe.. I am reinstalling all system drivers.
