Good evening experts,
I'm working on a computer for a friend who needs virus protection. The system is Win XP Media Center Edition Version 2002 SP 3. The system had a trial version of AGP V9 which has been completely uninstalled.
Once I downloaded MSSE for XP 32 bit from Microsoft, I ran the setup program. After successful windows validation I ran into a problem where I receiving an error indicating that the msse.msi located at C:\[random id] was not a valid installation package for Microsoft Security Essentials.
I did some research on the net about this issue and most suggestions pointed to doing an uninstall of the program (using various methods... running setup with /u, deleting certain keys etc). MSSE was not located in the Add/Remove Programs nor was there a folder for it under c:\Program Files. I checked in the registry and did in fact find several keys for MSSE... after backing up the registry I deleted all keys containing the words Microsoft Security Essentials or the acronym MSSE.
After a reboot, I tried the installation routine again. This time instead of getting the above mentioned error message for msse.msi, now it is referring to mp_ambits.msi which I suppose is Microsoft Antimalware (or possibly MS Forefront?) ... anyway ... that's where I'm at and I have no idea what to try next.
Oh one final thing I did do was I installed CCleaner on this system and cleaned the registry. Made no difference.
I also ran the Windows OneCare removal tool ... again no change in status.
Any suggestions ... or better yet a solution would be greatly appreciated. I've seen this issue discussed in parts on Microsoft's KB but I haven't found any suggestions that were applicable or actually worked.
