- Main site: http://grass.osgeo.org/
- First time users should explore the first steps tutorial after installing.
- Get the OSGeo4W Installer 32bit or 64bit. (400k network-installer, full download is approx 60-80mb)
- Generic installer help can be found on the main OSGeo4W wiki page.

Later Installation Update
- It is sufficient to re-run the installer which fetches the list of packages to then suggest available updates for the individual packages.
Lab Installation as offline set of packages
While the OSGeo4W installer is nice for individual installs, it may be problematic for institutional lab installs, where IT managers want to have stand alone applications that they can test, install, and remove easily. To install OSGeo4W-GRASS package as stand alone, see
- see also the non-OSGeo4W stand alone installer for WinGRASS
- Test, test test!
- While the GRASS libraries and modules are typically extremely well tested and stable, this new Windows install package is not. Because we are very confident in the underlying GIS code we hope that any problems due to the new Windows packaging efforts will be superficial and quickly resolved. You can help this process by reporting bugs: if it seems to be the fault of the installer report bugs to the OSGeo4W bug tracker, if it seems to be the fault of GRASS, report bugs to the GRASS bug tracker. You will need to create yourself an OSGeo ID to submit and comment on bugs. Bugs don't get fixed unless people point them out! It is expected that some issues related to spaces in the path names still exist, but we hope to have found most of these by now. Also it is likely that the wxPython GUI still has some gremlins in it, please help us find and fix them by reporting any errors you come across! Typically once found they are easy to fix. You can help to find spaces-in-the-path bugs by installing OSGeo4W into "
Program Files\OSGeo4W" and setting the GRASS data directory to "
Documents and Settings\username".
