Hello, Few days ago I installed Windows Vista Ultimate x86 (32bit) SP1 (integrated) and when I use the activation tool with the ASUS certificate or the HP, it doesn't work. It says it did it successfully, then RESET and it says 30 days remaining. When I click on the 30 days remaining it says on the top: 'This CD-KEY is invalid for activation'. This crack works on my Desktop PC (ASUS M2N SLI-Deluxe) without any problems, the same OS. I've tried another already activated OS (Windows Vista Ultimate again) and it still says 30 days remaining and on the next dat 29 and so on... Can some one help me why I can't activate the lap top and where is the problem ? P.S. I used to have XP there, but I had problems and just reinstalled to Vista Ultimate. The disk was not formatted for the install of the Vista.
