So I have 4 computers with Vista 64. I upgraded 3 to Windows 7. The fourth will not do it. I get The following issues are preventing Windows from upgrading. Cancel the upgrade, complete each task, and then restart the upgrade to continue. "You can’t upgrade 64-bit Windows to a 32-bit version of Windows. To upgrade, obtain a 64-bit version of the installation disc, or go online to see how to install Windows 7 and keep your files and settings. 32-bit Windows cannot be upgraded to a 64-bit version of Windows. To upgrade, obtain a 32-bit version of the Windows installation disc. " I know this OS is 64 bit for the heck of it I tried to do it 32 bit as well and I get the same answer. Any ideas?
