Your licence requires online access to verify its validity

Installation and Licensing

Since version 2016, as a theft protection mechanism, the licence requires connection to the internet at least every 30 days to be validated. An automatic validation is done 30 days after the last validation, if there is no internet connection a warning will be shown during 15 days, after this due time you won't be able to enter PowerFactory and will receive the following message:

Your licence requires online access to verify its validity!


You need to validate the licence. To validate the licence proceed as follow:

  • Connect to the internet. You can verify the internet connection following these steps:

- Open the Licence Manager by searching in the Windows Start Menu

- Click on Network Settings and then on Check Connection

  • Open PowerFactory. If it starts without warning message, the licence was automatically validated.

You can manually validate the licence at any time directly from PowerFactory, via Tools -> Licence -> Validate Licence. This can also be used to verify the number of remaining days until the next validation.
