User-friendly software for GWR is available from the authors. A new version of the software with Poisson and Logistic models, as well as a Gaussian model, GWR3x, comes with a Visual Basic interface that makes it particularly easy to use. With it, running GWR routines is simply a matter of pointing and clicking on the correct items in the menu-driven interface provided. The software and a manual are provided on CD. The cost of the software is €55(includes post and packaging) for academic users(Single Machine Installation) and €500 for commercial users(Single Machine Installation).

Please note that the software can also be run on UNIX: see Chapter 9 of Geographically Weighted Regression: An Analysis of Spatially Varying Relationships for more details of this. Also, code for GWR in R is available from Chris Brunsdon but note that this code is not an exact replica of the Windows-based program.
Please note that if you are currently using an earlier version of the GWR software, GWR 2x, we strongly recommend that you upgrade to GWR 3x. The latter program contains a substantial number of upgraded features and we can no longer support any enquiries about the use of GWR 2x.
If an upgraded version of GWR is released within six months of the date of purchase you can obtain a copy of the latest version (GWR 3X) at reduced cost (50% reduction). Please note that you must apply for this within the six month period.
