Well, I've tried many of the tips I read here in this forum without any success; plus from the total lack of any responses, I have to conclude that v5 will not run FS9 on Windows 10, at least not on my gaming computer. What a shame, I loved using an earlier version, either v3 or v4, on my old Windows 7 cptr but am giving up on this one. Sending the v5 package back to Amazon: it's too expensive just to throw it out...which is just what I feel like doing right now.!!!!
Oh well, I guess that's what you call "progress" or maybe 'planned obsolescence'.
