Questa 2021.1, Fatal License Error: Unable to checkout a viewer license

Many thanks to jster's solution kindly shared to the community, especially the PDF file.

I followed the PDF steps mostly for my Windows 10's QuestaIntel Starter FPGA Edition-64 2023.3 (coming with Quartus Lite 23.1std). My issue was the NIC ID output from my terminal's ipconfig /all is not the same as the NIC ID shown in Quartus.

After coping the NIC ID from Quartus and went to SSLC to use that NIC ID generating a new license, I placed it in a path and update the system environment variables. Then I was able to start Questa Sim.

It took me at least five hours resolving this issue, and the solution posted above was the one that actually helped me. Thank you again!

Here the erroe message:

# Start time: 10:00:11 on Nov 17,2023
# ** Note: (vsim-8009) Loading existing optimized design _opt2
# ** License Issue: License request for intelqsimstarter feature failed

# ** License Issue: Cannot find license file. (C:\flexlm\license.dat)

Few things you can do.

1. For Questa FSE, have you tried to regenerate the free license again?
2. To disable internet connection and rerun simulation
3. Or use diff connection and rerun

Let me know any update.

Let me know if there is any update.

I have the same problem. Was there any solution?
