Repairing Word's Files and Registry Settings (Word 97 only)
Word's setup program can be used to repair Word's registry settings.
Use Start Menu, then Run and browse to Word's Startup program (usually C:\Program Files\Microsoft Office\Office\Setup) and add /r or /r /y to the end of the line.
C:\Program Files\Microsoft Office\Office\Setup\Setup.exe /r /y
Switch Meaning
/r Reinstalls Word using the options of the last installation.
/y [Used with /r] Reinstalls Word using the options of the last installation without coping the files.
In Word 2000 choose Repair Word from the Help menu.
