I am having a similar problem. I migrated from a Windows 10 computer to a new Windows 11 computer and it has been a nightmare because of only a couple of items...one of them is RealityXP. No surprise there. I have four items from RXP...GTN 750/650 and GNS 53/430. I successfully brought over both GTN units and the GNS 530. The GNS 430 was the last one and I got a failed to download on the rxpGNS2-430-XPL.exe file.
It's not that it wouldn't run, it would not download. It can't be the internet or settings or anything common to the other three because I had no problems with them. It will not download the file. Flight1 has even reactivated the key. I don't know what to do next. I have tried everything I can think of. Someone I am sure can see what I am doing wrong.
Thanks.
