I am trying to upgrade from Vista Home Premium to Win 7 Ultimate using a DVD bought at retail. The upgrade process hangs while Gathering programs and settings, always at the 86% mark. Yesterday it hung at 6:00 PM and I let it run overnight -- at 9:00 AM next day it was still hung. No error message, no shutdown, just sitting there waiting. Following suggestions from various sources I have tried working from an empty start folder in Vista, and from a clean boot in Vista. Neither made any difference. I have turned off antivirus and taken down the firewall. My system is approved for upgrade by MS. I have tried starting the upgrade program from Vista safe mode and by booting from the DVD, but was not allowed to continue. I have done everything suggested by MS as a prelude to upgrading. My computer is a Dell Inspiron 530. I know I am not the first person to encounter this problem; I hope some subscribers to this forum have found a solution that they can pass on to me.
