PSIM 2026 License Error: Error 15 (6200@localhost) and Error 9

David_HR

Hi, I am a student at Ariel University using PSIM 2026. I have authorized my machine via Altair One, but I keep getting Error 15 (Unable to connect to license server 6200@localhost) and Error 9.

I already tried a clean reinstall and deleting the .lic folder, but the error persists. My Activation Key is: LDBSK-Y4NMU-EMS5S-3PERZ.

Please ensure that you follow Step 3 and 4 to install and activate the software using your student license key - https://community.altair.com/discussion/34207/instructions-to-access-the-free-altair-student-edition-now-in-altair-one#latest. Pls note if you are using the free Student Edition - It is a standalone license tied to one physical machine and does not support use on virtual machines.
