I have several add-ins that I no longer use, yet I can figure out how to remove them from the Add-Ins Available list in the Add-Ins dialog box. Whats the story?
There is no way to remove unwanted add-ins from the list directly from Excel. You must edit the Windows registry and remove the references to the add-in files you don’t want listed. Another way to do this is to move or delete the add-in files. Then, when you attempt to open the add-in from the Add Ins dialog box, Excel will ask you if you want to remove the add-in from the list.
