Hi Laurie, Does the issue occur while installing Windows 7 Upgrade Advisor or running Windows 7 Upgrade Advisor? I am assuming that some applications may block Windows 7 Upgrade Advisor from running, you can perform a Clean Boot, disable security software, then run Windows 7 Upgrade Advisor again. However, you can also search in Windows 7 Compatibility Center manually to identify if programs and hardware installed on your computer are compatible with Windows 7. BTW, to upgrade Windows Vista to Windows 7, please refer to the following guide: Upgrading from Windows Vista to Windows 7 Best Regards Dale
