LICENSE FILE TROUBLESHOOTING
81 ■ ALTERA SOFTWARE INSTALLATION AND LICENSING ALTERA CORPORATION
Quartus II Software
If the license.dat file contains an error in the license server name, or if the
path to the license.dat file is incorrect, the Quartus II software user interface
might run more slowly while the computer searches the network for the
non-existent license. If this problem occurs, edit the license file to correct the
error, or specify the correct path for the license.dat file.
To direct the Quartus II software to check the Altera website for an updated
license file, on the Tools menu, click License Setup. In the License Setup
page, click Web License Update. If an updated license file exists, the
Quartus II software automatically downloads and installs the correct
license.
Network Licensing Error: Quartus II or MAX+PLUS II
License File
You may receive the following message if you use the <port>@<hostname>
notation to specify the location of your Quartus II or MAX+PLUS II license
file. This error may occur if there is contention for the same port on the
license server machine.
Can't connect to daemon on license server -- make sure
lmgrd is running on server host and that it has the
correct port number.
To correct the error, verify that the port specified for the license server is not
in use by another application.
ModelSim-Altera Software
The ModelSim-Altera Edition software requires that the location of the
license file is set by the LM_LICENSE_FILE environment variable; however,
the location of the license file can also be set by the MGLS_LICENSE_FILE
environment variable.
