Now hopefully no one out there will need this post–especially because SQL Server discontinued support in 2011; however, because I learn something new everyday I feel compelled to put his post up. I came across a server that had automatic updates on and was trying to install SP2 for SQL Server 2005. It would error out and SQL Server would be shutdown. I was trying to install the update for SQL Server and the Analysis Server services. The error in the log was:
Product: Microsoft SQL Server 2005 -- Error 29528. The setup has encountered an unexpected error while Setting Internal Properties. The error is: Fatal error during installation.
When I tried installing the service pack manually, this error displayed in the GUI.
Service Pack 4 for SQL Server Database Services 2005 ENU (KB2463332)'
could not be installed. Error code 1603.
The resolution was to delete some registry keys, which is still gives me the Hebe-geebees, and these were the keys.
SQL Server Entries
HKEY_LOCAL_MACHINESOFTWAREMicrosoftMicrosoft SQL ServerMSSQL.1SetupSQLGroup
HKEY_LOCAL_MACHINESOFTWAREMicrosoftMicrosoft SQL ServerMSSQL.1SetupAGTGroup
HKEY_LOCAL_MACHINESOFTWAREMicrosoftMicrosoft SQL ServerMSSQL.1SetupFTSGroup
Analysis Services Entry

After I did this the installation went as expected. Now I just have to upgrade these bad boys.
