Hi I have Windows 7 Home Premium, I can get Windows 7 Professional. I have an older machine, just retired with XP Pro. My hardly used Cannon 'Canoscan D1250U2F' scanner worked on XP Pro. Bought a new machine , installed Windows 7 Home Premium and could not find any 64 bit drivers. Installed VMWARE and used it to install my own XP Pro installation as per the link Create an XP Mode for Windows 7 Home Versions & Vista - How-To Geek got XP working in virtual mode. great. Connect cannon scanner, it detects a new plug and play but will not seem to install the Scan Gear CSU TWAIN driver, the Wizard when pointed to the CD or the downloaded TWAIN driver I obtained from the Canon USA link Canon U.S.A. : Support & Drivers : CanoScan D1250U2F The XP Pro Hardware Update Wizard says ' The hardware was not installed because the wizard cannot find the necessary software. any suggestions? on how to get this damn scanner working?
