The Error Message Is:
Element Not Found.

This is the fix that worked for me:

You can use regedit (Start Menu->Run->Type “regedit”) to modify the following key:
HKEY_CLASSES_ROOT\TypeLib\{EAB22AC0-30C1-11CF-A7EB-0000C05BAE0B}\1.1\0\win32
and change the current value:
    C:\WINDOWS\system32\shdocvw.dll
to this:
   C:\WINDOWS\system32\ieframe.dll

More Details About this Fix
I was not able to find much details on when or why this registry entry was overwritten. The safe approach would be to make this fix, install your search provider, then restore to the original setting.

Miscellaneous
Being stuck with Bing as a search provider was annoying to say the least. However I did find that the results of the two search engines (Microsoft vs Goolge) were more similar than I have ever seen in the past. In other words, Microsoft’s result were actually useful.

I swing by this bank on the weekends because it is convenient but their ATMs are always broken. So when they recently replaced the old ATMs with these nice shiny new ones I thought I was set. They worked the first week but this Sunday both of their ATMs were locked up with IE script errors.

I think you have to be a web developer to find the humor in this because I’m sure the Spanish speaking patron who received this error wasn’t as amused as I was. Ay Caramba!

Maybe they need to clear the cache.
