Hello

Is the button visible again after restart Inventor? If so, I believe a reload don't destroy your button definition and somewhere there in your code raises an exception. The creation of new button fails, cause the definition already exists.

Take an additional look at this paper at page 13.

Hi

The problem is known, but AFAIK not solved. See http://forums.autodesk.com/t5/Autodesk-Inventor-Customization/User-unload-of-AddIn-mixes-Icons-every...

Has this issue been resolved? It appears to be my issued where the buttons won't reload after a manual reload of the add-in
