Request your permanent license

During the installation process, a file called hostid.txt will be created in the GAUSS 16 folder. This can usually be found in the /Users/myName/gauss16 folder unless you specified a different location during installation. Note that on some versions of Mac, it can be hard to find your Mac home directory using "Finder." Pressing COMMAND+H should bring it up, however.

To request your GAUSS license, fill out this form. The final line of myhostid.txt contains the hostid of your computer which you will need for your license request. If you have already closed your text editor, you will find the myhostid.txt file in your GAUSS installation directory. You may either copy and paste the contents or attach the myhostid.txt file.

Installing GAUSS for Mac in a Shared/Multi-User Environment

For all users to run GAUSS in a shared, multi-user Mac environment, please do the following:

1. Copy the entire contents of your GAUSSHOME to a location in which all users can access, such as: /Users/shared/gauss16

2. Change the name of the 'gauss' executable to 'gaussapp'.

3. Make a bash script named 'gauss' in the same directory (which should be /Applications/ The contents would be:

export GAUSSHOME15=/Users/Shared/gauss15

4. Make sure everyone has execution permission for this file.


Problem: When I try to run GAUSS, I get a dialog window that says "License Manager Error".

Answer: This means that your temporary license has expired and GAUSS cannot locate your permanent license. Browse to your GAUSS installation directory (/Users/myName/gauss16 by default) and check to see if you have a license file in that directory other than the temporary license. GAUSS license files end with a .lic extension.

If you have received your permanent license and cannot find it in the GAUSS installation directory, copy it there now and restart GAUSS.
