How to reinstall a specific Microsoft Office Application

Run regedit

Browse to the key:

My Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\X.X\YYY

X.X will be as follows, depending on your version of Word:

Word 2000 is 9.0

Word 2002/XP is 10.0

Word 2003 is 11.0

Word 2007 is 12.0

YYY will be the application you want to reinstall

Once you find the application you want to reinstall, right click the application folder, and choose Rename.

Rename it to OldApplication (Word would be changed to OLDWord).

This is a quick method of backing up your registry.

Close the Registry Editor.

Launch the application you want to reinstall
