I installed Streets and Trips 2004 complete with no problem. There is a window that asks If you want to install the complete program. I don't remember the exact wording. But the option IS there. Maybe try uninstalling it and then re installing.Rickkman said:Does anyone know how to get Microsoft Streets and Trips 2004 to function solely on the computer without having to use the CD. When I used the 2002 version of this software it automatically installed the program so that the CD was no longer needed.
