PowerPoint couldn't load the add-in -- an annoying message

[Ideen]

Greetings. I have Office 2007. I keep getting this annoying
message each and every I launch PowerPoint:

PowerPoint couldn't load the add-in

But I have not added any add-in and there is no add-in
Office > PowerPoint Options > Add-Ins > PPT Add-Ins
to be removed!

I had only added on add-in when using Office 2003 and
that add-in was removed sometime before I installed
Office 2007 and Office 2003 never complained.

I have re-installed to no avail. I have even removed the
entire application data folder of office and re-installed. Still
the annoying message shows up again.


Any hints?

Because it couldn't load it (for whatever reason) in the first place.
That, at least, makes sense.

Try this on for starters; let us know what it finds:
What add-ins are loaded?

Thanks Steve. One of the above options above revealed the culprit (I think).
The question is how to remove the culprit.

The culprit is an add-in I added when using Office 2003. It is called
SaveTheTree (characterized as a standard add-in). But I removed
this add-in (this is the one I mentioned originally). Some leftover
information must remain somewhere.
How do I find and remove the leftover info?

Many thanks!
