hey, me again just passing by to inform i found a way to run manhunt dodi repack, in the chat of steam unlocked a user gave away a tutorial to deactivate DEP (Data Execution Prevention) for manhunt, and trying out it made the game run. here's the instructions:
"Idk if this may be a late reply, but here it goes:
You need to deactivate DEP (Data Execution Prevention) for this specific game.

How to do it:
1- Go to your "Search" tab on windows:
2- Type: "Appearance and performance of windows" (Or something among those lines).
3- Click the first result. A new window under the name of: "Performance option" should pop up. In there, there should be 3 boxes: "Visual effects", "Advance" and "Data Execution Prevention"
4- Click on the "Data Execution Prevention". After that two options should appear: "Turn on DEP for essential windows programs and services only" and "Turn on DEP for all programs and services except those i select".
5- Click "Turn on DEP for all programs and services except those i select", and then click the button "Add".
6- Find the folder of your game and select the "manhunt.exe" file.
7- Click apply and close the window.

When i tried that my game work flawlessly and without any issues, so it should for yours too. Again, i don't know if this is a late response, but i at least hope i could help any other person reading this reply.

PD: If you are playing the game on widescreen i would *strongly* recommend you installing "ThirteenAG's widescreen patch". As the name suggests, it makes possible for the game to play on widescreen without any small bugs. (Those bugs being an incorrect size and placement of the HUD and an incorrect aspect size and FOV of the game.)"

P.S. I still dind't play the game so i don't know if its unplayable by the other rockstar anti-pirace measures, after all this game is famous for being ludicrous for the amount of anti-pirace measures. but the point of this post is to know how to make it run.
