Installation on Multiple Stand-alone Computers (Lab/Site)

Install Gauss 16 in Silent Mode

To install GAUSS in Silent Mode, you should be able to use the /quiet or /qn options with msiexec to perform a silent install. MSI packages export public properties, which you can set with the PROPERTY=value syntax on the end of the msiexec parameters. You can read the options for msiexec by just running it with no options from Start -> Run. Here is a link that you might find helpful:

To disable the automatic opening of the myhostID.txt file

To disable the automatic opening of the myhostid.txt file, you will need to FIRST create a script to make the a gauss16 folder on each computer and place an empty myhostid.txt file in the gauss16 folder. By having the myhostid.txt file in place, it makes the pop-up window not appear on install. Then do the silent install.

License Files

If you create one file that contains the hostid numbers of all of your computers that you are installing GAUSS on, we can create one license file that will work on each of your lab/site computers. This should simplify the licensing process. Please copy and paste the hostid numbers into your License File Request.


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 ( C:\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.
