I have a 1.6 GHz P4, Asus P4S333 systemboard 256MB PC2700 RAM with MS XP Prof (clean install)running. I installed Office XP (did not own but wanted to peak), then uninstalled it from ADD/Remove Applications, I installed MS Office 2000 then the SR1 packs (CD1, CD2). This worked well for several weeks. I (should have left this alone) uninstalled Office 2000, then installed Office XP again and when opened Outlook 2002 had the MS documented issue with "Error Message: MAPI Was Unable to Load the Information Service Pstprx.dll" (MS Tech. Note Q293058). They (MS)are still working on this one and I did not want to try the workaround. I used the "System Restore" to restore XP to just prior to my uninstalling Office 2000 SR1. I thought this worked untill I noticed that Word, Powerpoint, etc. would not run from the Icons. To make a long story short. How can I completely unistall all the Office reminants from XP and be able to reinstall either Office 2000 or Office XP so that it is stable and functional.
