Thanks for hanging in with me. Before I try Window over install, I have found something weird. I checked Windows explorer with the S&T discs(either setup or run) and there is a file with dialogue...Autorun.inf-Notepad and its says: Streets & Trips is not installed on your computer....Retail over trial: You have inserted the S&T run disc on a machine that has the trial version installed. Uninstall the trial version and install the retail version....Merlin, i have never had a trial version and can't find it with file search or windows explorer. In fact I deleted every S&T file and folder and started over from scratch. How do you like dem apples? Top of the morning to ya'....Woody
