If operating on a Windows OS, if you double click "Driver Setup" and get the following error message, try these steps:

If you have previously installed any other other graphic tablet/monitor driver software, please remove/uninstall all of them from your computer and reboot.

Close all programs and applications (including photoshop, illustrator, etc..) that are currently open, then go to the "Task Manager".

Locate the "Tablet Client Driver (32bit)" and "Wintab Service (32bit)" files then click "End task" to remove them.
