LDC Downloads

The installers below do not come with framework (basemap), which Roadsoft requires for installation. If you do not currently have Roadsoft, contact us depending on if you are Michigan agency or a non-Michigan agency.

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 roadsoft@mtu.edu.

Before Updating or Installing

  • Back up your data.
  • Prior to installing or updating Roadsoft/LDC, check your operating system version and SQL version for compatibility.
  • If you are in the middle of data collection, import any LDC data into Roadsoft.
