We have only installed Power InRoads Ss2 and Ss4 and after downloading the Delete Survey Graphics utility, it fails to run with the message "Could not find an installed version of MicroStation."
This utility needs MicroStation to run. It uses various DLLs that MicroStation has. You could install MicroStation, run the tool, uninstall MicroStation. You won't need to open MicroStation, it just needs to be on the computer. It will not work with just a Power product installed.
