Some of my My office 2007 enterprise apps stopped working.I could not repair
it as the setup would not run with the error "setup has stopped working".
So I had to uninstall it, which caused me numerous problems as that didn't
work either as I got errors about the package or installer being unavailable.
I eventually managed to get everything removed by doing it it from the
INSTALLER folder as per thjis article.

The setup.exe now runs, however it now gives me the following error

"Office encountered an error during setup. Error 1402. Setup cannot open the
registry key UNKNOWN\components\{GUID here}\{another GUID}

I have searched the registry and there is no such key anyway.

How can I get office to install again ?
