Office Troubleshooting: Certain Add-ins Keeps Getting Disabled
Symptoms
Certain Office add-ins keep getting automatically disabled even though you enable them back each time you launch the app.
Resolution
In most cases, navigating through "File > Slow and Disabled COM Add-ins" and clicking "Always enable this add-in" button will solve the problem. However, if that doesn't work permanently, a setting in the registry will help you keep the add-in enabled.
First, back up the registry (https://support.microsoft.com/en-us/help/322756/how-to-back-up-and-restore-the-registry-in-windows) to be able to restore it in case of any incorrect actions or unexpected results.
