I'm upgrading from Windows 7 Enterprise (which was actually upgraded from Windows 7 Ultimate 3 months ago) back to Windows 7 Ultimate (32-bit Enterprise to 32-bit Ultimate). After 4 hours or so, the install fails with the message "This version of Windows could not be installed. Your previous version of Windows has been restored, and you can continue to use it." This error is back at my Enterprise desktop, there's no error that I could see during install, just a message indicating that it was reverting everything. Oh and my monitor wouldn't start after the PC rebooted again. After another reboot I could see it was reverting everything.

I tracked down the error logs and here's the files (from C:\$WINDOWS.~BT\Sources\Panther): - setupact.log - setupmem.dmp

I know a fresh install is best, but I'm hoping to avoid that because I'd need a new hard drive.

The setuperr.log is here if you need it (the website wouldn't let me link more than 2 files) : - setuperr.log – Claudiu D. Mar 27 '11 at 13:57
"ultimate failed install" - that just struck me as funny :) – warren Mar 28 '11 at 20:37
@ClaudiuD.Did you solved your problem? – Mr.Hyde Mar 30 '15 at 20:19

You have a driver plugin that is causing it

[0x0808fe] MIG Plugin {e0cbf06c-cd8b-4647-bb8a-263b43f0f974}: BthMig: Failed to migrate bthport keys, bailing out


Run the W7 upgrade advisor and see what it says. If it flags any program or driver, remove them before upgrading.

From what I can see, it's a bluetooth driver. I do not own a bluetooth device onboard or plugged in my PC, that file is perfectly useless. Can I just delete it? Also, how do I do that? Also, W7 Upgrade Advisor says that except for one program I just uninstalled, everything is ok. – Claudiu D. Mar 27 '11 at 18:09
Is this a notebook? – Moab Mar 28 '11 at 14:15
No, it's my desktop. – Claudiu D. Mar 28 '11 at 20:26
Check my edit above.. – Moab Mar 28 '11 at 20:30
Well, the only drivers that would cause errors are the ATI video driver and the Catalyst Control Center, also from ATI – Claudiu D. Mar 29 '11 at 16:54
