| 3 | | Prerequisites: Before GSAS-II can be installed on your computer, you must install two software packages: python and subversion. These packages are distributed in a number of forms and are discussed below. Note that at present GSAS-II is only distributed via subversion. If you work at an institution with a firewall that blocks downloading files from subversion (uncommon, but known), contact your networking support department or arrange to perform the download from another location. |

| | 3 | Overview: Installing GSAS-II requires three separate steps. One must install a Python package which will interpret the GSAS-II package and one must also install the subversion package which is used to download and update the GSAS-II files from the server at Argonne. Once that is done, one can install and then run the GSAS-II system. To make matters even more complex, there are several choices on how each step can be performed, with different advantages. The Quick Install Instructions, below, choose the simplest options. Feedback on installation instructions is welcomed by |

| | 8 | For this, you will install the [http://www.enthought.com/products/epd_free.php Free Enthought Python Distribution (EPD Free)]. This is a 32-bit, light-weight version of the full EPD package, described in the [#Python Python section], below. Also, you will use the mini-svn/bootstrap kit, which contains a pared-down version of the subversion program and a batch file that installs GSAS-II from the APS subversion server. Detailed instructions on use of kit are found here: [ZipInstall Installation Instructions]. |
| | 9 | |
| | 10 | 1. To install EPD Free, download the .msi file from URL http://www.enthought.com/products/epd_free.php and click on it to invoke the windows installer. (See notes below about how to install without administrator privileges.) |
| | 11 | |
| | 12 | 2. Download file GSASIIsvn.zip from URL https://subversion.xor.aps.anl.gov/pyGSAS/install/GSASIIsvn.zip. |
| | 13 | |
| | 14 | 3. Open the downloaded GSASIIsvn.zip in the Windows Explorer -- you should see a single folder named GSAS-II. Drag this folder to where you would like to install the GSAS-II software. |
| | 15 | |
| | 16 | 4. Run the bootstrap.bat file to install the GSAS-II software. This will ask questions about proxy server (most users can select the default) and install the GSAS-II files in the location where the batch file is located. (See the [ZipInstall Installation Instructions] for more details.) Note that this batch file can be rerun at anytime to obtain the latest updates for GSAS-II. |
| | 17 | |
| | 18 | 5. Use the GSASII.bat file to start GSAS-II. The [ZipInstall Installation Instructions] explain how to create a shortcut for this. |
