ModelSim Xilinx Edition (MXE) - Fatal License Error: "Unable to check out a license. Run the ModelSim Licensing Wizard..."


Keywords: XE, dongle

When I attempt to launch MXE, a Fatal License Error window appears:

"Unable to check out a license. Run the ModelSim Licensing Wizard from the Start -> Programs menu to diagnose the problem."


This error indicates that ModelSim is not able to find a license file.

To solve this problem:
1. Make sure that you have obtained a license for MXE. If you have not yet received an MXE license, see (Xilinx Answer 9859).

2. Be sure that the LM_LICENSE_FILE environment variable is pointing to the license file. You can set this manually or use the ModelSim Licensing Wizard, which will set this environment variable for you.
