Invalid license for ModelSim?

I purchased an Arria10GX dev kit and downloaded Quartus Prime Pro (19.3). I have a license file Intel sent via email. I can run QP and aocl. I just downloaded ModelSim (19.3) but I get an error at runtime:

$ ./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.
 
$ ls  $LM_LICENSE_FILE
/home/okramer/intelFPGA_pro/1-RIWRVV_License.dat

Here are some relevant excerpts from that license file. I don't see any mention of modelsim. How do I get that?
