Reinstalling Windows and/or installing new Windows hardware will change the information used by Intuiface's licensing system to identify your PC. This change will invalidate the existing license key, requiring the acquisition and activation of a new key.
Ideally, a license should be released from a Windows PC before Windows reinstall or a hardware change. This way, once it is time to activate a new license. the old one has already been returned to the Intuiface license server.
The license release process depends upon whether you're talking about Composer or Player licenses.
Once your device is ready and Composer and/or Player are reinstalled, follow the standard license activation process to relicense the software.
