Hello Dominique. Just install Coastal Explorer the way you did on your other systems, then activate it using your Product ID. Here is the page on our site where you can download the full installer.
Note that the Product ID you sent is not quite correct and that’s actually a good thing, since we do not recommend posting your Product ID to a public forum like this one.
Also note that you may want/need to copy your voyage plan document (.nob file) from your old computer to the new one, so you have access to any routes, etc., that you’ve created.
If you have any problems with installation or activation, it may be simplest to help you via a phone call. 425-605-0985
