Ark: Survival Evolved, also known as Ark, is an Action-Adventure Survival Video Game developed by Studio Wildcard. The game is played in third or first person and offers both single and multiplayer modes.

It is available on various platforms such as PlayStation 4, Xbox One, Microsoft Windows, OS X and Linux, Android, iOS, and Nintendo Switch.

Lately, many PC users have reported that they are unable to play the game due to an error message starting with a failed confirmation: ARRAY_COUNT. The problem is not related to a specific map in the game. If you are experiencing the same problem, you can try the following solutions to fix the problem.

Launch the game directly from the installation directory

You may encounter this error if the Steam client is having problems launching the game or if the shortcut for the game is not working. In this context, the problem can be solved by launching the game directly from the installation directory.

  • Launch File Explorer and navigate to the Ark game installation directory. Usually this:
  • C: \ Program Files (x86) \ Steam \ steamapps \ common \ ARK \ ShooterGame \ Binaries \ Win64
  • Now run ShooterGame.exe and check if the game is working properly.

Run Steam / Ark as Administrator

With the latest version of Windows, Microsoft has made impressive improvements to the data protection and security features of its operating system. One of these features is to protect critical system resources with User Account Control. The specified error can occur when the game / Steam was unable to access an important system resource due to UAC restrictions. In this regard, the problem can be solved by running Steam / Game as administrator.

  • Steam will check the game files – this process may take several minutes.

Important: one or more files may not be available for scanning.
This is normal for most Steam games. The files that cannot be verified are local configuration files and should not be overwritten by this process. You can ignore this message.

Reinstall the Steam client

Before uninstalling Steam, move the / steamapps / subfolder to a safe location, then follow these steps:

  • Remove Steam
  • Reinstall Steam
  • Launch Steam
  • Stop the steam
  • Move the contents of the / steamapps / backup file to the new / steamapps / subfolder
  • Restart Steam

At this point, Steam should find all games without further action. In the worst case, if Steam does not recognize certain games as installed, simply reinstall them. The game will load in a few seconds / minutes and will be ready, since you only need to check the cache of the game content.
