With the recent release of Office 2010 RTM decided to go ahead and un-install the Office 2010 Beta 2, everything seemed to uninstall smoothly except at the end I received a 1402 error indicating that it could not open a specific item in the registry.
After checking the registry for any problems, found myself still scratching myself without an answer. Decided to be a little risky and force a refresh with secedit, opened the command prompt and typed in:
“secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose”
Once the command completed, attempted the un-installation of Office 2010 Beta 2 once more, this time it was successful.
This might not work for everyone, but in my case it worked great!
