Most common issues:
#1 - Add-ins are not installed (check if the Templafy Updater is installed)
#2 - Add-ins are not enabled
#1 How to check if Templafy Updater is installed
Check if there is a Templafy icon in the systemtray (bottom right hand corner of the screen)
Check for the application in Control Panel
#2 How to check if add-ins are enabled:
In Word / PowerPoint Choose File -> Options
Choose COM Add-ins and click "GO"
Check that Office Extensions are enabled
In some rare cases OfficeExtensions may end up in Disabled Application Add-ins.
It can be fixed by:
1) Go to Diabled Items in the Manage drop down menu and click Go
2) Click on OfficeExtensions and click Enable and then Close
3) Now OfficeExtensions should be in Inactive Application Add-ins where you can activate it as described.
