DRM: Unfortunately, no. I installed "DirectX End-User Runtimes (June 2010)", which the Microsoft website claimed included all of the DirectX 9.0 files, disabled Bitdefender's real-time protection, disabled .NET Framework 4.7, and then checked the box to enable Direct Play, and still am getting stuck on "searching for required files." I've been consoling myself with sessions of Sid Meier's Colonization (the original DOS version, not the Civ 4 spin-off). I know there's a "Planetfall" mod for Civ 4 which would give me at least some of the flavor of SMAC, but it wouldn't be quite the same as playing SMAC itself. (Back when I still had a Windows 7 computer, I played and enjoyed both SMAC and the Civ 4 "Planetfall" mod.) I suppose I should also do some more online research to see if there is anything else I should try to get SMAC/Alien Crossfire running on a Windows 10 computer, but I might take a break to do something else for a bit first, so I can troubleshoot some more when I'm refreshed.
