Recently I had problems with an Excel Add-in that was still trying to run, and generating error messages, even after being removed from the add-in list and uninstalled.
After much searching and trying suggested methods that didn’t work, I finally found a method that did work at:
Here are the steps:
- First, remove the addIn from Excel. After removing it, don’t reopen Excel yet
- Go to registry: Start -> Run -> regedit -> HKEY_CURRENT_USER\Software\Microsoft\Office\version\Excel\Options. Delete the registry of the addIn you want to remove. The data column will give you the hint.
- This is the key, remember to restart the computer to reset Excel. If you open Excel before the restart, it will register the AddIn in your registry again and you will need to start all over again
