Yes, I have checked all variations aircraft. For Pmdg install, I chose fsx steam edition then I chose the path
D: SteamLibrary \ steamapps \ common \ fsx for installation.
The pmdg file is in the fsx (navdata and SidStar). but no boeing pmdg in the Airplanes folder.
Sorry for the name in the forum, this is an error. I will try to change that.
thanks.
