Hello I found the right folder: it must be the folder conatining the "Official" folder: For me:
E:\Microsoft Games\Microsoft Flight Simulator\LocalCache\Packages
Don't go further and it works, find the correct one if you use Steam
Regards
Hello, nice to hear cause I just bought it thinking I could use it without the sim to at least prepare flight plans, and not at all, I'll wait a version for MSFS now hoping upgrade will be free for new buyer, patience brings many good things :)
