How to Fix xgameruntime.dll Error Code 126 on Windows

1. What Does “Failed to Load xgameruntime.dll Error Code 126” Mean?

The message failed to load xgameruntime.dll error code 126 usually appears when Windows or a game launcher cannot find, access, or correctly load the xgameruntime.dll file.

This DLL file is commonly associated with Microsoft gaming components, especially games installed or launched through the Xbox app, Microsoft Store, or Game Pass on Windows.

In simple terms, a DLL file works like a shared support file. When that file is missing, damaged, blocked, or not registered correctly, the related program may stop working and show an error code.

Common Causes of This Error

• Missing or corrupted xgameruntime.dll file
  This is the most common cause. If the xgameruntime.dll file is deleted, missing, or damaged, Windows cannot load it, leading to error code 126.
• Broken or incomplete Xbox Gaming Services
  The DLL depends heavily on Xbox Gaming Services. If Gaming Services is not installed properly or corrupted after a Windows update, the system may fail to load the DLL.
• Antivirus or Windows Security blocking the DLL
  Sometimes security software mistakenly quarantines xgameruntime.dll, or blocks it from loading. This leads directly to Error Code 126.
• Incomplete game installation or update
  If a game installation is interrupted or not fully installed, xgameruntime.dll may not be properly linked. This often happens with Xbox Game Pass downloads.
• Incorrect DLL registration or dependency failure
  Even if the DLL exists, Windows may fail to load it if dependencies missing, broken registry entries or runtime environment is not configured correctly.

Fix 1: Repair or Reset Gaming Services

Xbox gaming services are often responsible for handling game files. When this tool glitches, it can cause issues with games. Repairing Xbox Gaming Services can restore missing files, and if repairing does not work, you can reset it for a fresh start.

• Open Settings with "Win + I" and go to "Apps", then "Installed Apps" and click on "Gaming Services”.

  

• Click the "Options/3-dots" button and click "Advanced Options". Click "Repair" and after the repair is complete, test the game. If the issue is still there, you may click "Reset"

Fix 2: Using System File Checker (SFC)

SFC scans and repairs corrupted system files, including DLLs. It is one of the most comprehensive tools available on the Windows OS. Here are the steps:

• Open the Start menu, type "cmd," and select "Run as administrator," then run the command: "sfc /scannow.”

  

• Wait for the scan to complete and restart your computer once it is finished.

Fix 3: Check the Antivirus Software's Quarantine & Add xgameruntime.dll to the Antivirus Software Whitelist

Antivirus may remove xgameruntime.dll again and again. Adding it to the whitelist prevents repeated issues.

• Open the "Windows Security" app and go to "Virus and Threat Protection," then click "Manage Settings" and go to "Exclusions."

• Click “Add an Exclusion” and choose your folder where the problematic game/app is located, and confirm to whitelist it from Antivirus on your system.

  

Fix 4: Reinstall Xbox Gaming Services or Microsoft Store

Repairing or resetting Xbox gaming services may not always work, so reinstalling them is another option.

• Press "Windows + X" and select "Windows PowerShell (Admin)." Once it opens, run the following commands one by one:

  “get-appxpackage Microsoft.GamingServices”

  “get-appxpackage Microsoft.GamingServices | remove-AppxPackage –allusers"

  “start ms-windows-store://pdp/?productid=9MWPM2CQNLHN”

  

• Once the process is complete, you will get a Gaming Services pop-up on the Microsoft Store download page. Click "Get" on it and let the Gaming Services install completely to fix the issue.

Fix 5: Manually Register the DLL File

If all else fails, then you need to register the DLL file on your OS manually. Registering helps Windows locate the xgameruntime.dll file, and here is how you can easily do it using Command Prompt.

• Open "Windows Search" and search for "Command Prompt," then right-click to choose "Run as Admin"
