I am trying to upgrade my laptop form Window Vista Business to Window 7 Ultimate. I have run through the Window 7 Upgrade Advisor and found no issue. When it tried to installed Window 7, it will successfully complete Copying of files and will halt after attempting to perform expanding Files for a while. It just return setup failed and only option is to click OK and it stop installing. I already have the latest patch for Vista and turned of anti-virus or firewall. Any ideas what is happening here ?
Iv had a similar issue with xp to vista. Try upgrading within windows, then try booting from the cd and upgrading that way. If that doesnt work, try formatting and do a fresh install, remember to backup your files first.
Why not use the W7 Easy Transfer Wizard to save your files and settings, then do a clean install, it's easier and a better way to go. You will need to reinstall your programs.
To use the W7 Easy Transfer Wizard:
Browse to the DVD drive on your computer and click migsetup.exe in the Support\Migwiz directory.
Boot from the W7 dvd and choose custom install for a clean instalation.
