Many Steam users are having an issue with their game. They get an error message telling them steam_api64.dll is missing or not found when they open their game.

This is a very annoying issue. And trying to fix it can be just as annoying, because you’ll spend a lot of time reading suggestions on the Internet, and most won’t work.

But don’t worry! The following are a few methods that have helped many other Steam users repair the missing file.

Fixes to try

You don’t have to try them all; just work your way down the list until you find the one that works for you.

  1. Verify your game files
  2. Reinstall your game
  3. Copy the same file from another computer
  4. Update your device drivers

Method 1: Verify your game files

You can verify your game files on your Steam program to restore the missing steam_api64.dll file. To do so

1) On your Steam, click LIBRARY.

2) Right click your game, then click Properties.

3) Click the LOCAL FILES tab, then click VERIFY INTEGRITY OF GAME FILES. After that, click CLOSE.

4) Launch your game and see if this restores your missing game file and fix your error.

Method 2: Reinstall your game

You may also need to reinstall your game to repair the missing steam_api64.dll file. To reinstall your game on Steam:

1) On your Steam, click LIBRARY.

2) Right click your game, then click Uninstall.

3) Click Delete.

4) Click STORE, then search the game you’ve deleted.

5) Click Play Now.

6) Follow the on-screen instructions to download and install the game.

Method 3: 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 Files\Steam.)

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. 

5) Open your game. If this method helps you, you won’t see the steam_api64.dll missing error again.
