I am running into an issue when running service pack 3 for SQL server 2k5.

Here is a snapshot of the error:
07/04/2009 22:40:28.226 Registry: Opened registry key "Software\Policies\Microsoft\Windows\Installer "
07/04/2009 22:40:28.241 Registry: Cannot read registry key value "Debug", error 0

The databases and the analysis services are still on SP2 everything else was updated.

I have given the service account domain admin rights and I still get this error. I have searched and found not much on it.

Does any one have any ideas?
