This is very strange. I just got a new Sony VAIO laptop. I had a different one before but there were issues with it so I bought a new one after sending the old one back. It has SLIC 2.1 and I am running a legitimate copy of Windows 7 Home Premium x64. When I used the previous VAIO which had the same specifications, I was able to use Windows Anytime Upgrade to Ultimate... Now when I try it it fails! It just says it's unsuccessful and that's it! What do I do? I've tried multiple SLP keys!
