When trying to run Feko, I am encountering the following license error:
Altair Feko - SECFEKO Version 2021.1-14 from 2020-05-29
(compiled for target PC_WIN64_EM64T_MKL, 64 bit)
ERROR 9161:
An error occurred while checking out a licence
Altair License Manager: License error
Feature(s): GlobalZoneEU, HyperWorks, HWFEKOGUI
Error Code: 9
Error Description:
Feature not found
Feature: FEKOGUI
Error Code: 51
Error Description:
[LOCAL]
\Programs\Altair\Feko\security\altair_lic.dat - (Err: 51) Unable to use network license as a local license
License Path:
\Programs\Altair\License\altair_lic.dat;D:\Programs\Altair\Feko\security\altair_lic.dat

Would anyone know how to solve this? I have:
- Created an environment variable pointing to the license .dat file
- Ensured that the license file is named altair_lic.dat and not altair_lic.dat.dat
- Copied the altair_lic.dat file to the security folder of Feko. In my case
\Programs\Altair\Feko\security\altair_lic.dat - Made sure the MAC address of my device corresponds with the one seen in the license file
- Installed Altair License Manager and I am seeing this:

- Tried restarting the Altair License Server from Services.msc
- Restarting the computer
- Reinstalling Feko
- Installing an older version of Feko
Any help or troubleshooting tips would be appreciated.
