TechStations are really just glorified web browsers. All of the “smarts” are offloaded to RentEZ, to which the TechStations connect. TechStations are handhelds (TechStationPPC) or PCs (TechStationPC). They are stripped down for the very basic operations performed by rental technicians. The Install_Siriusware_TechStationPC_xxxx.msi installer is used to install TechStation on a PC. The c_techstation_9090_xxxx.zip files are used to install TechStation on the 9090 handheld.
