Right click start menu icon, select 'programs and features', click upper left 'turn windows features on or off', expand 'Legacy components', check the box next to 'Direct Play'. First I fixed the directplay problem by doing this: So if your Windows 10 is outdated or non-legit you might have problems. These are guided steps for how I got mine to work on a legit and currently updated copy of Windows 10. This method might not work for every single person but I don't see why it shouldn't. This was a nightmare trying to get this all set up and I wanted to help other ppl not have to also go through it without help.

I made this guide because I couldn't find any other comprehensive guide like this one anywhere online to help me fix Manhunt on steam so I took it upon myself to do it.
