Don't know the answer to your question but do know you can use the Navionics webb app page to view the same data online.
You need a live web connection though.
well there isnt a navionics app at the windows store (.......there isnt much of anything at the windows store.....i think windows has missed the boat).
What you can do is download an android emulator on to your win10 machine and then run your existing android navionics app.....so you wont have to buy another version of navionics!
there are several different emulators you can choose.
I havent used any but I guess mr google will help you choose the right one.
Navionics introduced the boating app in the Windows Store in August 2014 - that one would've worked on your laptop. Unfortunately they removed it, without explanation and no replacement is available. You're stuck with mobile operating systems.
As reported on the other thread, I've installed MeMu as it is up to date and gets good reviews. I haven't tried it with Navionics though as it's not needed on that PC. I have installed Raymarine and Vesper Marine apps and they seem to work just fine.
