Fix: isaac-ng.exe has stopped working

The Binding of Isaac is a beautiful indie game and it’s a randomly generated action RPG shooter with heavy Rogue-like elements.

Still, users are getting the “isaac-ng.exe has stopped working” message which means that The Binding of Isaac crashes to Desktop. The game is unplayable because of these problems and it often occurs right on startup. Fixing this problem shouldn’t be that difficult but still make sure to follow steps correctly.

What Causes the “isaac-ng.exe has stopped working” Error?

The thing which often causes this error message when playing The Binding of Isaac is broken or missing game files. This can applied both to game files in Documents where save files and preferences are stored and the main installation files in the directory where you installed the game.

The second most common cause for the problem is definitely outdated graphics card drivers which can’t support some in-game settings. You should update them as soon as possible. Finally, Steam Overlay seems to cause this problem in certain cases as it’s not fully compatible with plenty of games which don’t like anything being displayed over their window.

How to Fix isaac-ng.exe stopped working

Solution 1: Delete its Folder in Documents

Deleting the game’s main preference folder in Documents is a great way of sort of restarting the game without actually losing your save files, your progress but possibly solving your issue. The process is quite easy so make sure you try this method out before proceeding further.

  1. Navigate to the folder’s location in the File Explorer simply by opening a folder and clicking This PC or My Computer from the left navigation pane or by searching for this entry in the Start menu.

  2. Open the game afterwards by launching Steam and double-clicking the game from the Steam Library tab: Alternatively, you can locate the game’s shortcut on Desktop and run it if you haven’t installed the game via Steam. Check to see if the game crashes again.

Note: In the My Games folder, there should be a The Binding of Isaac Mods folder. If the method above has failed to work, you should try removing the content inside by moving it somewhere else to see if the game crashes. If the crashing stops, one of the mods you have downloaded is faulty and you shouldn’t use it anymore!

  1. If you fail to find this folder, open Steam, navigate to the Library tab, right-click on The Binding of Isaac entry, and choose Properties. Switch to the Local Files tab and click Browse Local Files. If the game is installed without Steam, right-click a game’s shortcut and choose Open file location.

  2. Once you locate the option, change the number next to it from 1 to 0 and check to see if the game still crashes!

Solution 2: Manually Install the Latest Graphics Card Driver

Talking about the importance of video card drivers when playing video games is just unnecessary as they are probably the first thing which may cause issues on your computers when it comes to video games crashing.

  1. Click the Start menu button, type in “Device Manager” afterwards, and select it from the list of available results by simply clicking the first one. You can also tap the Windows Key + R key combo in order to bring up the Run dialog box. Type in “devmgmt.msc” in the dialog box and click OK in order to run it.
