Although the license key was entered correctly, I cannot activate the full version.
Please make sure that you have entered the full license key correctly and without any typos.
A FrontFace license key looks like the following one; please note that the entire line is the license key that needs to be entered fully:
If this does not help, please compare the middle part of the license key (between the two dashes) with the activation code that is shown in the dialog when the Kiosk / Player Application is started.
If these do match, please enter the full license key again correctly and without any typos.
If these do not match, this license key cannot be used on this PC (either the hardware has changed or you issued the license key for a different/wrong PC). Please re-issue your license key.
