If this is the "MYTH" copy, you need to run SetupReg.exe, if it's another copy and there was no installer (Repack or etc off a preservation site) they probably didn't install the appropriate registry entries necessary for the game to run.

hi everybody the game is working, but there is a problem with the texture. The introductory videos are not displayed, there is no main menu in the game and no interface in the gameplay itself. There are no textures in the background of the pillars in the menu. how to fix it?
