MacroView DMS and Generator use Visual Studio Tools for Office (VSTO) which is a set of development tools for our add-ins in Microsoft Office. You may encounter issues with the add-ins being disabled and to troubleshoot this issue you can enable error/alerts to indicate why the add-ins are being disabled.
Enabling VSTO error/alerts
1. Open control panel > System > Advanced system settings

4. In the Variable name field, enter VSTO_SUPPRESSDISPLAYALERTS. In the Variable value field enter “0” and click OK.
5. Go to File > Options > AddIns in the Office application and try and enable the DMS/Generator Add-in. You should now get the full error of why the add-in is not loading.
