I have received the following message: Excel caused an invalid page fault in moduel EXCE.EXE at 0187:302a2eb7...then it proceeds to give several Registers & also a Stack dump. This computer has w98 os had pre-installed MS Office Prof 2000sr1 of which I have no cd. What happened is that I attempted an add-on to convert a ss to Access, it DID convert ok. But then when I rebooted it gave the above message. I've been able to save ss from the 'newer' computer as 'send to A:" on a disk & take it to my older w98 computer that has MS Prof97 and am able to view any of the ss copied from the newer computer. I have a few thoughts & would greatly appreciate any comments. #1. buy a register cleaner soft ware. #2. Uninstall only the Excel 2000 & install the old Excel 97 of which I do have a cd for. (The other MS Office Prof2000 do continue to work, ie: Word, etc) Anyone out there able to share their comments?
