Keep seeing a steamclient64.dll error on Steam?

One of the worst things that you can experience on Steam is the steamclient64.dll error message. The Steam app won’t run on your computer when this message occurs, and you cannot access your game library. 

This can be really frustrating, especially if you have a scheduled game night with your friends or you’re looking to enjoy your weekend after a tiring week. 

However, instead of playing games, you are stuck with the steamclient64.dll error on Steam. 

The steamclient64.dll is a legitimate file needed by Windows to run Steam. This includes a set of instructions on how to execute the program and a few driver functions. 

Based on what we know, the steamclinet64.dll error on Steam usually occurs when the actual file gets corrupted or deleted from your hard drive. It may also be due to improper installation of Steam, errors on the Windows system, or outdated software versions. 

Today, we’ve decided to make a guide for fixing the steamclient64.dll error on Steam. 

Let’s get started!

1. Restart Your PC. 

The first thing you should do when encountering the steamclient64.dll error on Steam is restart your system. Some files needed by Steam may not have loaded correctly the first time you boot Windows, which triggers the error message. 

See the steps below to restart your Windows PC: 

  1. On your keyboard, press the Windows key to access the Start Menu
  2. Next, go to the Power Options tab. 
  3. Finally, click the Restart button to reboot Windows
Restart Windows

Once done, try launching Steam to check if the problem is solved. 

2. Run Steam As Admin. 

If Steam can’t find the steamclient64.dll file, it may lack permission to access specific folders on your hard drive. To fix this, run the Steam app as an administrator to bypass any restrictions on Windows. 

Here’s how you can do this: 

  1. On your desktop, right-click on the Steam app and choose Properties
  2. After that, go to the Compatibility tab. 
  3. Finally, enable the Run this Program as an Administrator option and click OK
Run Steam as Admin

Try launching Steam afterward to see if the steamclient64.dll error would still occur. 

3. Update Your Graphics Drivers. 

Although Steam is just a game launcher, it still needs your video card to function correctly. If you can’t launch Steam on your computer, try updating your graphics card drivers. 

Follow the steps below to update your drivers: 

  1. First, press the Windows + X keys on your keyboard. 
  2. In the Quick Access Menu, click on Device Manager to launch it. 
  3. Now, click on Display Adapters and right-click on your video card. 
  4. Lastly, choose the Update Driver option and follow the prompts to continue.

Once done, go back to Steam to see if the problem is solved. 

4. Update Windows. 

Another reason why Steam won’t launch on your computer is if your system is outdated. Windows releases frequent updates to its operating system to ensure it is compatible with all the latest apps and programs. 

If you keep seeing the steamclient64.dll error on Steam, follow the steps below to update Windows: 

  1. On your keyboard, press the Windows + I keys to access Windows Settings
  2. After that, go to Update & Security
  3. Finally, open the Windows Update tab and click Check for Updates

After updating Windows, go back to Steam to see if it will launch without errors. 

5. Scan for System Errors. 

Some of your system files may have gotten corrupted, which causes Steam and other applications not to work. Fortunately, Windows has a built-in file checker tool that scans your directory for corrupted files and automatically repairs them. 

See the steps below to use the system file checker on Windows: 

  1. First, press the Windows + S keys on your keyboard and look for ‘Command Prompt’.
  2. After that, click on Run As Administrator
  3. Lastly, type ‘sfc /scannow’ in the Command Prompt and hit the Enter key.

Once done, try launching Steam to see if the problem is solved. 

6. Run Malwarebytes. 

Your system may also be infected by malware or virus, which consumes your application and system files. If you’ve noticed other applications running into errors as well, download Malwarebytes on your computer. 

You can use its ‘Full System’ scan feature that searches your entire hard drive for infected files. Malwarebytes will attempt to repair them if possible or remove them entirely from your system. 

7. Manually Copy Steamclient64.dll. 

If you still see the steamclient64.dll error on Steam, we suggest that you manually copy the .dll file to Steam’s folder. You can do this by copying the steamclient64.dll file from a working computer. 

You can also download the .dll file from the internet, but you can expose your system to further risks as you won’t know if the file you downloaded is a legitimate steamlclient64.dll file. 

Once you’ve secured a copy of the steamclient64.dll file, navigate to the steam or game folder and paste the file there. 

If that didn’t work, follow the steps below: 

  1. First, paste the steamclient64.dll file to C:/Windows/System32
  2. After that, open Command Prompt with administrative privileges. 
  3. Lastly, type ‘regsvr32 steamclient64.dll’ and hit the Enter key to proceed.

Once done, open the Steam app and check if the error message would still occur. 

8. Reinstall Steam. 

If manually copying the .dll file did not work or you can’t secure a copy of the file, you can always reinstall Steam on your computer. This way, you’ll have the latest working copy of Steam installed on your system. 

See the steps below to remove Steam from your computer: 

  1. On your computer, access the Control Panel and click on Uninstall a Program
  2. Next, locate the Steam app from the list of programs installed on your computer. 
  3. Finally, right-click on Steam and choose Uninstall

9. Report the Problem to Steam. 

If none of the solutions above worked out for you, we suggest that you let the experts take over. 

Go to Steam Support and get in touch with their customer service to report the issue you’ve been experiencing on the Steam app. Provide your account details, the exact error message you’re getting, and other information that can help speed up the process.
