Well, I don't know if anyone still watches this, but I'll give it a shot.
Has anyone gotten this to run completely successfully on Windows10? Or with an installation of Civ3Complete from GoG.com or maybe Steam?
I've tried with mine from GOG with windows10 and it seems to work some, but definitely not completely. Mine was only putting saved screen shots for the map that I had just started into the folder I designated for saved games, and some files with the extension ".set". No ".sav" files, even when it found an 'acceptable' map.
I was also having what seemed kind of like the problem bluejay had a few years ago:
Conquests and Mapfinder seem to run fine, except that after MF finishes its first group of iterations, it won't reload Conquests, but just sits there, or sometimes pops up the report screen.
Except my install is not in program files, but just C:\GOG\Civ3Complete\ ....
I'll give more details if I get a nibble =).
One question in general: If mapfinder is truly working, will it take you through the various windows as it executes them, kind of like selenium automates web browsers, if you know what that is like. Or does it do it in the background somehow? Mine is definitely not going through all the screens visibly, and from the comments I've read so far, it seems like maybe that behavior is implied... Mine is displaying messages at the bottom as if it is running through different steps like "Starting new game", "Saving game", "Verifying..." and "Waiting for Conquests to start..." This last one is where it will get stuck, even long before it reaches the max number of iterations I've set.
