Keep crashing? Here is a fix that worked for me.
I really loved this game, and I want everyone else to be able to experience it. Once I upgraded from windows xp to windows 8 the game became unplayable, it would crash so often completing a single level was impossible. Here are some simple fixes that worked for me. My fix did not involve altering any game files.
First, if you are suddenly unable to run the game, or maybe it is the first time you are trying to run it, and it crashes at start up, go to your steam library, right click hotline miami, go to properties, click the upper tab that says “local files”, and finally click “verify integrity of game cache”.
Next, find the .exe of hotline miami. If you created a desktop shortcut that will work, if you didn't create a shortcut go to steam\steamapps\common\hotline_miami\hotlinemiami, right click it. If it is your desktop shortcut, follow this same procedure. First thing, right click and hit “run as administrator”. Now, go to properties, click the top tab “compatibility”, and under “compatibility mode”, check the box for “run this program in compatibility mode for:”, then set it to “Windows XP (Service Pack 3).
Done, very simple. This worked for me, and I hope it will work for you.
