Using the Applications Installer Wizard in GAUSS 13+

GAUSS 13 (and later versions) features an applications installer wizard that simplifies installing applications. To install an application using the wizard, first save the application ZIP file to your computer, either your GAUSS 13 (or current version) folder or a temporary location.

To access the applications installer wizard, go to Tools->Install Application:

Tools->Install Application

After selecting Install Application, you should see a dialog like this:


Select Next to proceed; you will be prompted to choose the application ZIP file.

Select the application zip file

Click Choose; the wizard assumes that the ZIP file is located in your current working directory, so if it is in another folder, browse to that location and select the application that you want to install. Note that GAUSS in-house applications begin with the prefix app_.

Select the application ZIP file

Once you have selected the file, click Open, then Next to install the application. That's it; if the application was successfully installed, you should see a dialog like this:


You can confirm that the application is ready for use by opening the Source tab and looking in the list of libraries available in the Library Tool. All installed libraries will be listed there.


  1. When installing an application, a message appears stating “The file “________” already exists. Do you want to overwrite this file?”. This is because the application or an older version of the application was previously installed and a file with that name was found during installation. You have the choice to continue with the installation or to cancel as appropriate in your situation.
  2. When running an example that came with the application, an error appears stating “Can’t open <filename>”. This is because some of the application examples come with sample data files. You need to change your working directory to be in the examples directory to run these examples. The examples directory will be inside the GAUSS home directory, for example C:\gauss13\examples.
  3. When running an example or your own code that uses the application an error appears stating “Library not found G0290″. This means that the library file (which ends with an .lcg extension) is not in the correct location. Most likely the application has not been installed. If you have more than one version of GAUSS on your computer, it may have been installed to the home folder of one of the other GAUSS installations.
