Unable to Activate Add-In

Peter Newman 1 Reputation point

I am trying to activate the tws add-in as seen in this image


It is not available if I go to manage excel add-ins


Nor is it in disabled items


Vendor support suggested I ask Microsoft as they think there is a problem with a registry item.

Thank you for your help.
