Sharepoint and IE Error "Library Not Registered"

Hi All
Happy New Year to one and all ... only the best for the coming year :).
First post for the new year .... let make it a happy one.
So users have been complaining that the custom drop down menus in SharePoint don't work.
Here is an example of the Error

Hmmmm ..... whats going on here .... ok so first i add the URl to the trusted zones and allow script ot be downloaded and enable ActiceX control and all those warm and fuzzy things.... but to no avail ..... *Phew*
Doing a bit of research on the Net led me to here.

Basically the reason i got was that some Spyware or Malware installed on the client PC replaces some of the DLL's.
SOLUTION: Run Office Diagnostics
So users with "Office 2007" should:
1. Save and Close all Office Client Application(Word, Outlook, etc)
2. then click the Office Button ....

3. Click "Word Options"

4. then click "Resources"
5. then click "Diagnose"

6. then click "Continue"
7. then click "Run Diagnostics"
8. and viola ..... let he diagnostics run and problem Solved....

tell next time ... happy moss'ing ... :)
hope this helps someone ... :)
Thanks again
Bradley
