Program (latest official release, test builds and archive of previous versions):http://sasgis.org/download/ Attention! Servers with maps can be updated after the release, so the maps are strongly recommended to update anyway!
unpack the program somewhere, for example, c: \ SASPlanet, but not in c: \ Program Files and not in c: \ Program Files (x86)
unpack the maps into the Maps directory (since they are newer than in the archive with the program). You should get SASPlanet \ Maps \ sas.maps \ and SASPlanet \ Maps \ plus.maps \.
