When attempting to upgrade from Vista Home Premium (32bit) to Vista Ultimate (32bit) can an upgrade error - upgrade fails. The Vista Upgrade advisor tells me that the
NVIDIA GeForce 9600M GT will not work in Windows Vista:- "This device will not work in Windows Vista. For more information, please go to the device manufacturer's website, Windows Marketplace, or contact your retailer." How can I proceed to upgrade to Windows Vista Ultimate? Is this just a Vista Ultimate upgrade issue or is this display adapter truly not supported on Vista (even though I have a HP Pavilion laptop with one installed running Vista Home Premium). Any help or advice appreciated.
