The system requirements for Roadsoft, Roadsoft Mobile and the Laptop Data Collector can be found in the Roadsoft Manual.


If you are running Roadsoft or LDC 7.8 or earlier, or your basemap is Michigan Framework Version 15 or earlier, do not install or update to the new version of Roadsoft. Contact Roadsoft technical support at
