I just installed Office 2000 on my HP laptop (running windows xp). Everything was working fine until a bit later I installed Office 2000 SR-1 to get rid of the Outlook password prompt. Now I can't open any Office programs (Outlook, Word, Excel, etc) without that program immediatly closing. I tried installing SR-2 and 3, but that didn't make any difference; I also ran a full system scan with Norton, but didn't find any viruses. Help!
