How to change PRTG license from Freeware to Trial?



I am using freeware (100 sensor limit) and I am officially in love with PRTG :) it's amazing .

Is that possible to switch this 100 sensore freeware to a fully functional 30-days trial license (without limits in number of sensores); I am planning to buy PRTG.

Glad to hear you love PRTG! ;-)

It is not possible to revert a freeware to a trial once the trial period has exceeded. If you download PRTG from our website under https://www.paessler.com/download and install PRTG, it will start as trial and automatically revert to freeware after 30 days.

For more information about licenses and license keys, please see manual section Enter a License Key.
