I have ReTrace Deluxe. Looks like the only software that will work with it is their own program. You can download it from the Celestron website. I have windows 7 and had to run it in compatibility mode for it to work. The buttons at the top of the page (Download POI, Save POI, etc.) are greyed out but STILL work if you know where to click on the screen. I ran the program first but it failed to connect to my ReTrace Deluxe. Then I marked on the screen where the buttons I needed were located. I ran it in compatibility mode and the program works if you know where to click on the screen to load tracks etc. You can use a highlighter to mark your screen the first time you run the program to help later.
