As with any VSTO add-in, UpSlide can be deactivated even when behaving normally. We have a reactivation service we recommend you enable to prevent disruption to your users.
Deactivations can could be caused by
- An Office or Windows update
- Office crashing when UpSlide is running and the user being prompted to deactivate UpSlide
If that happens UpSlide can be reactivated manually by following this procedure.
To avoid this extra work and/or potential IT involvement each time the Add-in gets disabled, we include a reactivation service with UpSlide called UpSlide monitoring service. UpSlide monitoring service runs under local service accounts and monitors all the registry keys that get modified when UpSlide is deactivated. If a deactivation change is detected, the service simply reactivates UpSlide.
Note that this service will not interfere with manual deactivation.
How to Deploy the Reactivation Service using Support.exe Tool
In the Support.EXE tool there is an option to install the Reactivation Service automatically. This can help when a single user is having issues with UpSlide deactivations.

Here is the detailed list of the keys monitored and the subject to be altered by Upslide monitoring service.

In addition, some keys are used by the Office Applications to disable add-ins. Disabled add-ins are added as values in the following user registry hive keys:
The values corresponding to UpSlide in the above keys will be deleted by the service if needed.
