Installing Network monitor (web) on a private network VM.



Good Day, After installation. I have problem activating the free license on a VM not connected to the internet.

I have read the instructions... but did not resolved it, neither do i fully understand the steps.

I get a computer id, but where do i get the activation code from ?

Hello David,

Thank you very much for your knowledge base post.

With a Trial Edition license key, you can experience unlimited functionality of PRTG during the 30-day trial period. Your installation automatically switches to a Freeware Edition afterward.
A freeware uses the same trial license key and the switch will happen automatically.
