Acquiring and Installing GME

This page contains the information you need to determine if GME is comptabale with your version of ArcGIS, the link to the GME installer, and installation instructions.

GME is a stand-alone program that can be started from the Windows Start button -- Programs -- SpatialEcology. It has both a GUI interface (mouse-driven) and a command line interface for scripting.

GME currently has dependencies on R and ArcGIS. Use the table below to identify compatible versions of the software. If you are upgrading any of the dependencies, it is recommended that you use Control Panel to uninstall the old version first.

GME 0.7.* does not require statconn and the link to R has been relaxed so that GME works with almost any version of R from R-2.12 onwards. This greatly simplifies installation and upgrade of GME.

GME versions and are equivalent, but one is complied for ArcGIS 10.0 SP4 and the other for ArcGIS 10.1.

ArcGIS 10: it is very important to ensure you have the Microsoft .NET Framework 3.5 installed BEFORE you install ArcGIS 10, otherwise the ESRI .NET libraries will not be installed!

Detailed Instructions

GME uses the open source, statistical software R. It is recommended that you install R yourself before running the GME installation program (you can install GME first, provided you install R before working with GME).

Step 1: Uninstall any previous versions of GME using Control Panel Add/Remove Programs (Programs and Features in Vista/Win7).

Step 2: If required, upgrade R and install the required libraries by starting R as an Administrator (Vista/Win7: right click, Run as Admin) and running this command in R:

install.packages(pkgs=c("CircStats", "odesolve", "coda", "deldir", "igraph", "RandomFields", "ks"))

Step 3: download the GME installation file using the link in the above table, unzip it, and run setup.exe.

Step 4: Test the R connection: start GME. Go to Help, then Citation. You should see citation info for R and GME. If you get a red error message then the connection to R is not working and needs to be fixed.

Troubleshooting Installation

The installation program does not run

You must use the setup.exe program, not the gme.msi program, to install GME. The former performs a variety of checks on your system and helps you install missing components. Also, run it with Administrator privileges (an admin account in WinXP, or right-click and 'Run as Administrator' in Vista/Win7).

Problems with R

If you install R to the default location, and install the required libraries as described above, there should be no issues with R.

To get the most recent version of R, go to the R website and click the 'CRAN' link on the left hand side (see picture below). Select a mirror site near you from the list, click the 'Windows' link on the next page, then the 'base' link on that page after that, and download the R installer called 'R-2.15.0-win32.exe' (note that the version number you see may be different than this example).

Other issues

Supported Operating Systems

This software should run on any Windows XP, Vista or Windows 7 system (32 or 64 bit). I do not know how well it runs on terminal servers.

Registry problems

GME does not enter any data into the registry. Your operating system may enter data into the registry for the Control Panel, Add/Remove Programs (Programs and Features in Vista/Win 7) program.

Uninstall GME.

You can uninstall using Control Panel Add/Remove Programs (Programs and Features in Vista/Win7) where it is listed as "Geospatial Modelling Environment".
