Greetings,
I find out why the games does not work here is how to solve the problem for players who have the same problem as above
step 1: move the installation folder of the "CIV4" games to the "VaultCache" folder otherwise the games crash automatically
below are the steps to move the cradle.

I thank you for reading and taking the time to watch I wish you good games to you!
