You can also refer on how to do license setup.

To set up a fixed license file (single user, single computer), follow these steps:

1.Make a backup copy of any existing license.dat file for reference.

2.Save the license.dat file (that was attached to the licensing email you received) on your local hard drive.

Store the license.dat file in a directory named C:\licenses\flexlm (Windows) or /usr/local/flexlm/licenses (Linux).

When you specify the license file location, use only alphanumeric characters and do not type any special characters or symbols, such as !$%^&*<>, empty spaces, or non-English characters in the license file directory name. Special characters may invalidate the license file location.

3.Use one of the following methods to specify your license:

Specify the license within the Quartus® Prime software.

Specify the license file using an environment variable.
