## 4.3.3. Set Up a Fixed License

To set up a fixed license file (single user, single computer):
1. Create a security copy of any existing license.dat file.
2. Save the license.dat file on your local hard drive. The preferred location is:
• Linux:
/usr/local/flexlm/licenses
• Windows:
C:\licenses\flexlm
Note: If you save the file in other location, make sure that the path contains only alphanumeric characters, and do not type any special characters or symbols, such as !\$%^&*<>, empty spaces, or non-English characters.
3. Start the Intel® Quartus® Prime software.
If the Intel® Quartus® Prime software cannot detect a valid license file, the License Setup Required dialog box prompts you to license, evaluate, or buy the software.

4. Select If you have a valid license file, specify the location of your license file, and click OK.
The License Setup page on the Options dialog box appears.
5. In the License file box, specify the full path name of the license.dat file, and click OK.
Alternatively, you can specify the license file location by using the LM_LICENSE_FILE environment variable. However, the location that you specify in the License Setup dialog box supersedes LM_LICENSE_FILE.
