WLTrialExtendExpiration

The WLTrialExtendExpiration function allows extending the current trial period. To extend the trial period in an application, we recommend using Trial Extension keys (Generated by WinLicense). The WLTrialExtendExpiration function is suitable for those applications which cannot accept WinLicense trial extension keys by design.
