Hello
Apologize for the delay. Could help check again the setup. But before setting up Questa/Modelsim, would you kindly help check, whether your machine is supported or not (OS) by referring to link below:
https://www.altera.com/support/support-resources/download/os-support.html
For Questa software, you must set an environment variable the location of license. you need to specify location of the license file using the LM_LICENSE_FILE system variable (click/checkout the Use LM_LICENSE_FILE variable). You need to set your LM_LICENSE_FILE environment variable to point to the license that Intel provides. c:\intel\license.dat or something similar.
Please stop and restart PC after assigning.
To make this entry, you may perform a windows Search for "System Variables" and then click on "Edit the System Environment Variables" and then click "Environment Variables". Be aware that you must add the entry in System variables, not user variables.
(if you print "system v" instead, you can see it).
You can also refer this following YouTube for license setup. https://www.youtube.com/watch?v=Ob9ei5lMgGE
