Wrong Host ID

When I generated the license file for the first time, the Ethernet card on my computer was disabled so the licensing process somehow grabbed my wireless card’s MAC address as the HostID.

That works for a while, but now I have a problem when I connect my machine to the router via the ethernet card.

Regardless of whether the wireless card is present or not, the license check fails since it only recognizes the Ethernet card’s MAC address and it’s not the same one used during the generation of the license key.

What do I do now? Can I regenerate the license file?



Please open
Start -> PGI Visual Fortran -> PVF Command Shell
and run the following in the window.

  1. lmutil lmhostid
  2. ipconfig /all
  3. lmutil lmhostid -hostname

In both the environments where you are connected and not connected
to the ethernet.

Send those outputs, along with your current working license to

and we will create a proper license for you.
