Using an activation key is one of the two options to set a license for i-net PDFC and enable the comparison feature.

When submitting the activation key, i-net PDFC will contact the license server to acquire a full license. This will set the start date for one year licenses and bind the activation key and license to your current system.

Hint: Using an activation key requires i-net PDFC to connect to the internet. In case there is no connection available, please contact pdfc@inetsoftware.de for an offline license. Please send along the activation key and the 'Current Hardware ID' displayed in the license panel.
