Installing GAUSS 13 for Windows
Run the installer
The first step is to run the GAUSS installer. To run the installer, browse to the location where the GAUSS installer was downloaded. The downloaded file should be named either GAUSS_13_Win_64.zip or GAUSS_13_Win_32.zip. Double-click on the zip file and you should see the GAUSS Windows Installer File. Double-click on this file to begin the installation. Follow the installer’s instructions to complete the installation.
NOTE: GAUSS 13 must be installed in a location in which the user has read and write privileges.
Request your permanent license
At the end of the installation process, if you do not already have a permanent license on your machine, notepad will open a file named myhostid.txt.

To request your permanent license send this information to license@aptech.com. You may either copy and paste the contents or attach the myhostid.txt file to the email. Please also include your serial number and whether the machine on to which you are installing is for your office, home or laptop.
Run GAUSS
To run GAUSS, either click on the desktop icon, or the start menu shortcut. GAUSS comes with a temporary license that allows you to run GAUSS for a few days, so that you do not have to wait for your permanent license to begin using GAUSS.
Install your permanent license: Single User License
When you receive your permanent license, simply place it in the directory in which GAUSS 13 is installed. The default location is: C:\gauss13. To confirm that your license file is installed correctly, start GAUSS and from the main application menu bar select Help->About GAUSS.

The license type field will tell you if you are using a permanent or temporary license.
Troubleshooting
Problem: When I try to run GAUSS, I get a dialog window that says “GAUSS Initialize failed: Error Code: 491″.
This means that your temporary license has expired and GAUSS cannot locate your permanent license. Browse to your GAUSS installation directory ( C:\gauss13 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.
