Microsoft Office Spell Checker not working

As anybody knows who's ever had to support Microsoft Office installs, there are a myriad of problems that you may run into.  One such obscure problem popped up a few days ago.  One of our employees complained that her spell-checker had just stopped working.  Well, after reviewing the problem sure enough no matter what I did it wouldn't work, and by not working I mean it was a dead link with no response after selecting it.  After some troubleshooting I came to the conclusion that the problem had occured because the user had installed Microsoft Office 2007 over top of 2003 and this had corrupted the spellchecker. I found the solution from this thread on lockergnome.com

 I've detailed below how to fix this in a few steps.  As always, if your not experienced in editing your registry, please don't tackle this as you may create even more problems.

1. Press the Windows Key+R on your keyboard to bring up the RUN box.  

2. Type "regedit" press enter. No quotes of course.

3. When the Registry window appears navigate to:

HKEY_CURRENT_USER\Software\Microsoft\Shared Tools\Proofing
Tools\1.0\Override\en-US

4. Find these 2 entries (DLL and LEX), entries that don't exist anymore from the OLD installation.

5. Rename these to "oldDLL" and "oldLEX". 

6. Close registry. 

7. Reboot
