Hello,

I encountered the same issue that Simon describes below and could not
find a solution posted anywhere. Here is how I resolved the issue:

Shorten the length of the add-in description. (set in the document's
"comment" property)

It appears that excel (possibly just the add-in manager) does not
support add-in descriptions beyond a certain length (I'm guessing 255
characters - I haven't verified this.) I encountered the issue
described when my description text was 368 characters long.

Reducing the length of the description eliminated this behavior.

Or possibly it was something altogether unrelated, at least the
problem went away :)

We have an Excel-add that has been added via Tools|Add-ins and works.

However, when you go back to Tools|Add-ins you get the message

"Cannot findaddin c:\xxxxx.Delete from list?"

If we answer No, add-in continues and we can verify that theXLAdoes
exist.

If we exit Excel and re-start, Excel does not complain about
theXLAbeing
missing, i.e. the registry OPENn is set correctly.

Any ideas why Excel is displaying this message even though the Add-in
filename and path is valid...
