Thread: Upgrade vista to Windows 7

I have Windows vista on my desktop computer system. Right now I am planning to install windows 7 on my system. But I am not able to upgrade. What is the issue? It is compatible issue or any other? Can anybody tell me what steps I should follow to Upgrade Windows vista to Windows 7?

I think the upgrade problem is due to MSDN release. These problems come up because of the 64-bit to 64-bit, it’s better to installs fresh copy of the Windows 7 rather than upgrading. There are smaller amount possibilities of software incompatibility in Windows 7 with older version of Operating System.
