If you open the rights-management, the infoBoard Client crashes.
Please check the following Windows setting:
1. You have to do a right-click on the screen, on your desktop
2. Open the display settings.
3. Under the heading Scaling and arrangements in the dropdown selection, 'Change size and text, apps and other elements', the infoBoard software only supports the 100% setting.
