|Screen Pass Version 6.8 User Guide|
When you purchase Screen Pass you will receive a license key that must be applied to each workstation running Screen Pass. The license key is required for Screen Pass to remain fully functional after the demo period has expired.
The license status for a workstation is shown under the "System settings" button on the Screen Pass tab.
The alphanumeric key may be "pushed" using Group Policy or applied to an individual workstation using the "License" tab on the Screen Pass Administrator.
Another option is to enter the key directly into the registry using regedit or a .reg file:
HKEY_LOCAL_MACHINE\SOFTWARE\Birch Grove\Screen Pass\Admin6\LicenseKey
