For those who are having problems with launching the game, starting game videos, follow these steps (try all options as administrator): https://support.gog.com/hc/en-us/articles/360016041693-Total-Annihilation-Kingdoms-potential-solution-for-launch-crash?product=gog Now, If your game is launching but doesn't start games try to change the resolution, the game doesn't work well in some resolutions, try the last resolution on that bar, don't try 4k resolution. That's what worked for me. Cheers from Brazil.
