I have a strange problem with an older computer running windows 98 and the 2000 works suite (with word). Every time word is opened it instead opens a illegal operation dialog box and if you click details it says "invalid page fault in module MSO9.dll." I've tried everything I can think of to no avail. I've tried starting office in safe mode (with /safe and by holding ctrl). I've tried renaming/moving normal.dot. I tried renaming the hkcu\software\microsoft\office\9.0, which made office act like it was reinstalling when I opened word, but then, same error. I tried "repairing" word from it's installer. I've even uninstalled word via it's uninstaller and then ran microsoft's word 2000 removal tool, rebooted and then reinstalled word off the disk. Even with a complete reinstall it just craps out and does the same "illegal operation, page fault..." message every time it's opened. It's very frustrating. I'm wondering if there are remnants of word still left in the registry or spattered about the computer even after using the word removal tool that might be causing the problem. I also am thinking it could possibly be some conflict with the rest of the works package or even with IE 5. I really don't know what else to try (other than reformatting the computer and starting over, which I really don't want to do). If anyone has any ideas, I'd love to hear them! FWIW: This guy has the same problem. I have searched the net quite a bit on this, but haven't found any solution yet. Edit: I did see this from the MS KB. I already tried reinstalling like it says, but I didn't do the rename mso9.dll and winword.exe. I guess I'll try that, but I sincerely doubt that renaming before the repair will have any effect if a full reinstall doesn't work.
