Do you have Rob Bovey's Code Cleaner?

Rob Bovey's URL:

So thither I went, and fetched it down, and ran it.

Now when I fire up Excel, there is the Code Cleaner
attached, and it immediately generates an error -

Run-time Error '1004':
Method 'VBE' of object '_Application' failed

on this (the last) line of Auto_Open

''' Create the VBE menu.
Set gclsMenuHandler = New CMenuHandler

NOT a very auspicious beginning....
