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

Before Updating or Installing

  • Back up your data.

Roadsoft Update History

Component Updates
Culvert Filters
  • Added 'GPS Located' filter field.
  • Added filter fields for new Rating elements: 'Structural Deterioration', 'Invert Deterioration', 'Section Deformation', 'Joint/Seams', 'Blockage', 'Scour', 'Slab', 'Abutment'.
Culvert Reports
  • Fixed truncation exception running Culvert Rating report if a rating memo was longer than 255 characters.
Drainage Structure Filters
  • Fixed bug filtering on Pipe Length Units field
Export to File
  • Added Federal Aid (true/false) field to Road Export.
  • Fixed bug which would not include Road shapes for Gravel segments with only TAMC Validated ratings of zero.
  • Fixes to form so it doesn't display as too tall to fit on widescreen resolution. Ensured that the Field Order (up/down) buttons actually work.
Filter Builder
  • Added code to prevent deletion of Road Filters in use by other layers' filters.
  • Fixed 'Error converting data type varchar to float' exception deleting a Linear Mark Filter
LDC Import
  • Fixed bugs which would cause 'String or binary data would be truncated' exception on import into Roadsoft
  • Fixed selection information for Road selection to not display '0: Not rated' for road segments that had a treatment that did not affect the rating. The previous rating (if any) should be displayed instead.
  • Fixed bug in resetting Main Window Dock State which would not reset the map windows (Map Layers, Mini Map, Selection Info, etc.)
  • Fixed 'Cannot access a disposed object' when the Legend Builder was opened and closed and then the Legend Form was opened
Pavement Management
  • Fixed Project Planner and Strategy form sizing to be more viewable on a widescreen resolution.
  • Fixed possible 'infinite' loop opening a saved ESL analysis caused by deleted Surface Subtype.
Road Module
  • Fixed some inefficient code that would slow down showing the Road Module and cause delays switching segments when the database had a larger amount of Routine Maintenance entered.
Sign Filters
  • Added 'GPS Located' filter field.
Work Order Control
  • Removed autosizing from Work Order Control form grids--user can now resize columns manually.
