Problem With Registry Keys While Trying To Install SQL Server 2005 Express

I've been trying to re-install VS2005 & MS SQL Server express, and I've hit a snag trying to install SQL Server express.

I started by trying to use the automatic uninstaller for VS and had problems so I tried manually uninstalling it (bad idea), which didn't work either, so I re-installed VS completely, then uninstalled it using the automatic uninstaller. I then tried installing, which worked for VS2005, but it didn't work for SQL Server. I've tried 3 times now, and each time it says SQL Server 2005 failed to install.

I checked the summary.txt log found in C:Program FilesMicrosoft SQL Server90Setup BootstrapLOG and from what I understand, it seems that I don't have priveledges to change some registry keys. This has me really lost because I'm installing as Administrator, as you can see from the log below, so I should have access to the registry. Administrator is the only account on the computer so I know I haven't messed up priveledges from another account.

I've included the contents of the summary log below if anyone can make any sense of it and has any ideas I can try.
