Did you get your internet working?
I had a good clean install on the test rig but wasn’t happy w/ not getting the internet working so I tried a upgrade install from Win7 Ult, booting from the OS, that failed rather fast so I tried some registry tweaks to make it look like Win7 Enterprise or Business, both those upgrades failed too @ the same place.
1 of the error messages said:
The following issues are preventing Windows from upgrading. Cancel the upgrade, complete each task, and then restart the upgrade to continue.
Your current version of Windows is more recent than the version you are trying to upgrade to. Windows cannot complete the upgrade.
So I tried a clean (keyless) install of Vista Enterprise SP2, then upgrading that to 8, that failed 25 minutes into the install after the last reboot.
Here is a photo I took of the Windows 8 Eula that only shows-up when doing a upgrade install.
