Tony,
That should be possible. You would still have to register the DVD, but install the charts into the folder that MaxSea looks at to find charts. I'm not sure what that directory would be and if you could possibly create your own folder and add that directory into MaxSea to tell it where to look. You will have to contact MaxSea tech support for an answer to that question. To run the registration program, go to Windows Explorer, right-click the drive the DVD is in and choose Explore. The next window will list all files on the DVD. Find Register.exe and double-click it to run. This will take you through the registration wizard. All chart files are found in the BSBCharts folder. You can copy these files to the appropriate directory on your hard drive once the DVD is registered. You also need to have at least version 10.2 of MaxSea in order for it to work with these charts.
