Many Steam users are having an issue with their game. What happens is an error message pops up when they open their game on Steam that says:

  • The problem can’t start because steam_api64.dll is missing from your computer.
  • The code execution cannot proceed because steam_api64.dll was not found.

This is a very annoying issue. You can‘t play your game because of this error. You may not know how to fix it, and probably you don’t even know what the missing file is!

But don’t worry! The following are an explanation of the missing file and a few solutions that have helped many other Steam users restore the missing file.

What is steam_api64.dll?

Steam_api64.dll is a component of the Steam program. It is required by some Steam games to access Steam features and functionalities (such as anti-cheat and digital rights protection) so that they can run properly.

  1. On your Steam, click LIBRARY.
  2. Right click your game, then click Uninstall.

Fix 3: Restore the steam_api64.dll file

You can also fix your steam_api64.dll missing issue by restoring the file from a reliable source. To do so, you can follow these steps:

  1. Go to DLL-Files. Use the search box to look for the DLL file that is missing from your computer.
  2. Once it got a hit in the database, you will see the available dll files. You can then click the file and follow the instruction on the page to download the file to the designated location.
  3. Note that sometimes you may find that there are multiple files available. Mostly you can simple pick the highest version. But when the versions are the same, it could mean that the files work for different architecture. To find out the architechure of your system (whether it’s 64-bit or 32-bit), you can open Windows Settings and check the System type.
Missing DLL files could imply a bigger issue, and sometimes on the system level. If the problem persists, you can use a system repair tool like Fortect to scan for system issues.

Now check to see if this fixed your dll file missing issue.

Fix 4: Copy the same file from another computer

You can also try copying the missing file from another computer. To fix your issue, you should make sure the computer:

  • Runs the same operating system as your computer does;
  • Has the same game installed.

To check if the other computer has the same operating system:

  1. On your own computer, click the Start menu in the lower left corner of your screen. Then type “cmd“, right click Command Prompt in the result, and click Run as administrator.
  2. Type “control /name microsoft.system” and press Enter on your keyboard.
  3. Do the step 1 to 2 for the other computer.
  4. Make sure the Windows editions and system types of both computers are the same. (If not, it’s recommended that you find another computer.)

To copy steam_api64.dll:

  1. On the other computer, open File Explorer (by pressing the Windows logo key and E on your keyboard), then go to the folder where Steam is installed. (By default, it is C:Program FilesSteam.)
  2. Type “steam_api64.dll” in the search box.
  3. Copy the steam_api64.dll file and paste it to a flash drive or an external hard drive.
    You should check the location of the file you choose and make sure it is in the directory of the game. And you should also remember the location, as you’ll need to paste the file to the exact same location on your computer.

  4. On your computer, go to where your Steam is installed, then paste the file to the same location as where you copied the file on the other computer. 

Now launch your game. If this method helps you, you won’t see the steam_api64.dll missing error again.
