I have an office machine that's running a full OEM Windows 7 Professional x64, and I've been handed a full retail Windows 7 Ultimate x64 DVD and key to upgrade the machine with. I had assumed that Microsoft would facilitate this process, instead I got the following error when I run setup.exe and clicked "Install Now":
Error: 80070005 - Windows was unable to create a required installation folder
I followed the instructions at: http://support.microsoft.com/kb/968003
This is all being done a BootCamped Mac.
But now I'm wondering if I've made a mistake by doing so.
Can anyone help?
