A clean install involves removing TurboCAD, then deleting some files and folder that get left behind, then reinstalling the latest build of TurboCAD. This is not a 100% clean install, as we do not mess with the registry or delete the documents folder.  

  • Using the programs and features control panel remove all versions of TurboCAD and symbols installs.
  • Delete all of these folders.
