That is typical is NORMAL.DOT is corrupt. You said you tried, but really didn't list what was tried. Did you delete all the NORMAL.DOTs?
I am using Windows XP Pro with Office Xp Pro. Yesterday I went to open Word and it will not launch. I tried the suggestions posted here: http://www.personal-computer-tutor.com/NNTWord.htm and it did not resolve the problem I uninstalled Office, and reinstalled and the problem still occurs. All of the other office programs work fine. I checked in task manager, and WINWORD.EXE is listed as running and I cannot shut it down using end process.
