I think I got it:
Download this file to a temporary folder.
Shut down all Adobe programs.
Set a system return point to allow you to rollback the changes should anything go wrong (if your system supports it).
Unzip it to C:\Program Files\Common Files\Adobe\Shell.
You could quite likely already have either of the DLL files. No matter.
Run aiicon.dll.reg by double clicking it.
Run psicon.dll.reg by double clicking it.
That should do it
