modelsim_ae licensing not working - modelsim_ae licensing not working Hello, I am an Intel Intern trying to get modelsim altera edition working properly on Ubuntu 16.04. I have the complete Quartus Prime 18.0 Standard Edition and I have Quartus working and the licensing is set up. However, when I attempt to run modelsim, I get an error about the licensing. First, I tried to run modelsim through the Quartus GUI, which generated the attached report. Then, I attempted to run it through command line with ./vsim and this produced the following output: $ ./vsim Unable to checkout a license. Make sure your license file environment variable (e.g., LM_LICENSE_FILE) is set correctly and then run 'lmutil lmdiag' to diagnose the problem. Unable to checkout a license. Vsim is closing. ** Fatal: Invalid license environment. Application closing. So I checked to make sure my variable existed: $ echo $LM_LICENSE_FILE 1800@altera02p.elic.intel.com Then I used lmutil as the above output suggested (I copied the directory I ran this command from too): ~/intelFPGA/18.0/modelsim_ae/linuxaloem$ ./lmutil lmdiag lmutil - Copyright (c) 1989-2014 Flexera Software LLC.

It appears that the diagnostic tool does not believe anything is wrong, so what could be causing this? Any assistance would be greatly appreciated.
