Your registration key not working is probably because you have details for a previous version of NXPowerLite and are trying to use it to unlock the latest version. Am I using the correct version of NXPowerLite Desktop?
If your key is for an earlier version, you can access downloads for older software in the NXPowerLite Products All Downloads area.
Alternatively, you can upgrade to the latest version at 60% of the price of a full license when you validate your current Registration Key at our online store.
Have valid upgrade assurance?
Any customers who have current Upgrade Assurance cover should have received the latest key free of charge. If you haven't received it yet, please contact us for your new registration key.
