I wanted to play an old game called heroes of might and magic 4, but whatever i tried it doesnt let me launch the game, it just shows me black screen for couple seconds and then just closes, no crash report or anything, i tried everything that came to mind, but still doesnt work, tried turning off all startup apps, restarting pc and then launching, one time it worked, the game oppend but closed after couple seconds again, i had a simular problem with hunt showdown on steam, but the thing where i close the startup apps worked

FOUND THE SOLUTION
i just needed to disable msi from launching with windows idk why it causes the game to crash, maybe because they are not compatable or smth
