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the file downloaded file is moved to a computer not connected to the internet it will install a working, but slightly out-of-date GSAS-II version.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):

• ​https://subversion.xray.aps.anl.gov/admin_pyGSAS/downloads/gsas2full-Latest-Windows-x86_64.exe

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".

Click on "More Info" and a "Run anyway" button is displayed, as above. Click on "Run anyway" and the installer will start:

• This screen shows the version number of GSAS-II that is contained in the installer. Later this will be updated, if an internet connection is available. 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 by pressing "Next", selecting options as you go.

• Pressing Next the 1st time brings you to the License Agreement window shows you the article we ask you to cite, as well as the use terms for Python and packages, as below. You must agree to continue. The License for use of GSAS-II is found in the source code for the package; for convenience the full text from this screen and the GSAS-II license are shown below.

• We have only tested with install for "Just Me". Use of "All users" is probably not an ideal choice in any case, as likely only the installer would be able to save options and do updates.

• The Installation Location may need some attention. The default works for most people, but there have been problems reported with Python installations when the install location contains spaces and or non-ASCII characters. GSAS-II has been tested and appears to work fine in locations with spaces in the name (like C:\Users\Brian Toby\GSASII) but this has not been tested with other types of text. You may wish to install in C:\GSASII. Whatever location you supply must be a directory that does not already exist or must not contain any files. Please make a note of where you install GSAS-II (use of right-click will allow you to copy the text.) This can be useful to recover from an incomplete installation and will be referenced below as <Prefix> so that if you install as C:\GSASII then <Prefix>\subdir\file.txt means C:\GSASII\subdir\file.txt

• If you choose a location with spaces in the name you will get a warning. You can use the "Back" button to select a new installation location.

• The Advanced Installation Options are not that important, but the suggestion is that you do not select either option. The default for the second option is usually to have the second option selected. This makes lets other packages make use of the version of Python you are installing for GSAS-II. This is not likely to cause any problems with GSAS-II, but if you are using Python for code development, you are suggested to install another copy of Python and work with that.

• At this point, click on the "Install" button and allow the installation of files to start. Expect the installation to speed along until the "Setting up package cache ..." message is displayed, and at that point things slow down and several minutes will be needed before much happens.

• After that message appears, several steps will happen with no displayed messages. A 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.

• The last step will be to download the latest version of GSAS-II. You are at that point asked to enter a proxy address. Most people will leave that blank and hit return.

Then click on "Next" and "Finish". to complete the installation.

GSAS-II Information & Anaconda license:

====================================================
This is a single-download installer for GSAS-II. It includes other
software such as subversion (svn, used to update GSAS-II), a Python 
interpreter and a number of Python packages required by GSAS-II. The
file you are running will install GSAS-II, Python, etc. and will then
run the bootstrap.py script to create shortcuts and will use svn to
update to the latest version of GSAS-II, if an internet connection is
available. Noet that the bootstrap.py script can be rerun manually to
obtain updates.

*** Note that while this installer can be rerun to install the software
in a new location, once these files are installed, they should not be
moved. ***
