FaceReader License Locked to Unknown or Old PC (Floating/Fixed Deactivation Required)
Last updated: Oct 29, 2026
Problem
A user cannot activate their FaceReader license because it is still registered as active on another computer that is no longer accessible or known.
Details
Occurs when a PC is replaced, reimaged, or lost without first deactivating the FaceReader license. Also occurs after moving a PC to a new network environment. Affects both SBLK software licenses and dongle-converted licenses.
Solution
1. Contact Noldus Support and provide your license key or order number.
2. Support will locate the license on the license server and remotely deactivate it.
3. Once deactivated, open FaceReader on the intended PC and activate the license normally.
4. As a best practice, always deactivate your license via Help > Deactivate License before uninstalling FaceReader or retiring a PC.
