I added "LM_LICENSE_FILE" to environment variables and still get the same issue. Account activation e-mail will be sent in few. Click Create Account and create your account. This means you cannot compile technology libraries of ASIC or FPGA such as Xilinx. Altera provides a free license limited to Altera FPGA. From Altera website, downloading Quartus II web edition. Click Sign in to access account on upper right corner. There are two opportunities to get a legal free Modelsim license: If you are a student, you can get a free student edition at Mentor website link.

Update: Another site suggested adding an environment variable to the location. Free tools download and installation guide ( Xilinx WebPACK and Modelsim XE download and installation guide ) 1. However I have placed the license file where the error says it is looking for the file - in C:\Modeltech_pe_edu_10.4a\win32pe_edu\ however I still get the error. # Please go to and download an updated copy of the ModelSim PE Student Edition. # - it is not for this version of ModelSim PE Student Edition. # ** FATAL ERROR: ModelSim PE Student Edition licensing failure due to one or more problems with the license key such as: If i double click on the entity I get this error down in the transcript window: ** Error: ModelSim PE Student Edition license key file not found at C:\Modeltech_pe_edu_10.4a\win32pe_edu\.\student_license.dat. When I right click on my entity to try and select "create wave" this button is greyed out which it is not in the tutorial. I have the student version installed with the license key placed in the root install directory. I'm following a tutorial by Intel ( link to youtube video) which says that after analysis and synthesis I go to tools -> run simulation tool -> RTL simulation. I'd now like to setup a test bench in order to simulate the code. I have written some VHDL code which compiles fine in Quartus Prime Lite edition.
