64-bit Windows: Installing GSAS-II with a single download

A single download installer can be used to install the latest version of GSAS-II. If the file downloaded file is moved to a computer not connected to the internet it will install a working, but slightly out-of-date GSAS-II version. Note that 64-bit Windows- or later is required.

Download this .exe file (~0.4 Gb):

download of installer

Install Python

Run the downloaded file (gsas2full-*.exe). This can be done by pressing the "Run" button in the web browser if that is an option. You will likely see some sort of message protecting you from this "unknown and possibly malicious app".

Windows warning After clicking on "More Info"

Click on "More Info" and a "Run anyway" button is displayed, as above.

Note that the installer suggests closing all applications. It is wise to save work in other applications, but closing them seems a bit excessive. You will need to pass through several windows, selecting options as you go.

Installer starting

  • The License Agreement window shows you the article we ask you to cite, as well as the use terms for Python and packages. You must agree to continue.

The last step will be to download the latest version of GSAS-II.

  • A "DOS' (cmd.exe) window will open, some tests are run and a desktop shortcut will be created to start GSAS-II. That shortcut can be copied or moved to other locations. Double-clicking on it will start GSAS-II.

Problems/comments

If the process completes properly, you will see a GSAS-II desktop shortcut; double-clicking on it will then start GSAS-II, opening two windows. If the process does not complete, see here

Note: A spurious error message saying "Failed to run post install script" will be displayed with older installers. Press "Ignore" as this does not actually represent a problem.
