How to run installation for DirectX 9.0c, 8.0, 7.0 games in windows 8, 8.1, 10, vista (tutorial)

To run the installation of any DirectX 9.0c, 8.0, 7.0 etc in windows 8, or 8.1 or 10, or vista, you need to do the following:
-> open the Run, (click on start, and search for "run", and open that file).
-> in the Run windows write the following:  "Path to setup.exe file or autorun.exe file" -DXInstalled

Examples:
F:\autorun.exe -DXInstalled

and once you open that file in this way, you will never encounter that message that says: "This game requires directx 9.0c. Please visit http://www.microsoft.com/directx to download it."

Once the installation is finished, if you encounter an error that says: "This game/software requires hardware acceleration", you just need to make sure that you run that program in compatibility mode for "windows xp sp2, or sp3"... and also make sure that you "run it as an administrator"
