I maintain a small intranet app hosted on a mate's computer. Couple weeks back he had issues with the computer not booting up, so (without my knowledge) he ran it down to his local computer store and they reformatted and put all his programs back on.
The computer is running WinXP Professional, and has Service Pack 3 on it. I've tried installing SQL Express 2005 many times but it keeps failing, and research is telling me that SP3 and SQL Express don't play together nice. This is also the only thing I can see that has changed since the reformat (it used to run SP2).
I've read Microsoft's guides on how to remove SP3 but none of them work, to me it seems the computer place reinstalled XP with SP3 disks. SP3 doesn't appear in Add/Remove Programs and the uninstaller doesn't appear in the Windows folder.
Screenshot of the system, any ideas of how to remove SP3 would be great.
