When the add-in is run for the first time, you are prompted to activate the automatic loading of the Infront Analytics add-in at Excel startup.
To view or change this setting, click Options in the Infront Analytics ribbon.
Automatic loading is activated when the Load Add-in at Startup option is checked.
In case of problems, you can double-check if the add-in Effull is checked in the Excel add-in list (click File > Options > Add-ins, then Go).
