Office 2007 Beta 2 Technical Refresh Uninstall
September 15th, 2006
After the problems from my earlier log blog note … like a genius I’ve sussed it in the end 
.
Looks like it didn’t like the fact that my My Docs was re-located as a mapped network drive. Changed that and it started to give decent error messages.
I did have to manualy completed uninstall Office 2007 Beta 2 though ! Simplest way was to remove all the files and anything I could find in the registry then load the Windows Installer CleanUp Utility to clear the MSIs down . All installed and running cleanly in Windows Vista R1 x64 at last.
