Not sure which version you have. The Map Create 6 version I have works with my Windows 7 pc. Granted the graphics are horrible by todays standard. Plus I'm not so sure the maps are accurate, I have several waypoints that show up on land, and I know I marked them while in the boat, in the water. I didn't get around to uploading them last night. Maybe if I get time tonight after packing Ill work on it, otherwise Ill do it in camp this weekend.
