Encountering Windows Error Code ERROR_26 can be frustrating, especially when it disrupts your workflow or gaming experience. This error commonly appears when a software or game fails to launch or function properly due to missing or corrupted files, permission issues, or other system conflicts.
Don’t worry! This detailed, step-by-step guide will walk you through practical solutions to fix ERROR_26 quickly and efficiently. Whether you’re a beginner or a seasoned user, these easy-to-follow instructions will help you get your system back on track.
What is Windows Error Code ERROR_26?
Before diving into the fixes, it’s helpful to understand what ERROR_26 is. This error typically indicates a failure to initialize or load a game or application because certain dependencies (like files or system components) are either missing or inaccessible.
Common causes include:
- Missing or corrupted installation files
- Insufficient user permissions
- Software conflicts or outdated drivers
- System file corruption
Step 1: Restart Your Computer
Sometimes, the simplest solutions are the most effective. Many system errors, including ERROR_26, can be resolved by simply rebooting your PC. Restarting clears temporary bugs and system glitches.
How to restart:
- Click on the Start menu > Power icon > Restart
- After your PC restarts, try launching the problematic software or game again.
If the error persists, move on to the next steps.
Step 2: Run the Application as Administrator
ERROR_26 can occur when the program does not have the required permissions to access system files. Running the app with elevated privileges often resolves such issues.
How to run as administrator:
- Locate the application’s shortcut or executable file.
- Right-click on it and select Run as administrator.
- Confirm any User Account Control prompts.
- Check if the error still appears.
If running as admin works, you can set this permanently:
- Right-click the app > Properties > Compatibility tab > Check Run this program as an administrator > Click Apply and OK.
Step 3: Verify Game or Software Files (for Games or Apps via Steam or Other Platforms)
If your program is a game downloaded via Steam, Epic, or similar platforms, corrupted or missing files might cause ERROR_26.
For Steam:
- Open Steam and go to your Library.
- Right-click the game > Properties > Local Files tab.
- Click Verify integrity of game files…
- Let Steam scan and repair any corrupted files automatically.
- After completion, try launching the game.
For other platforms, look for similar “verify” or “repair” options.
Step 4: Update Your Graphics Drivers
An outdated or faulty graphics driver is a common culprit behind errors involving games or graphic-intensive applications.
How to update drivers:
- Press Windows + X and select Device Manager.
- Expand Display adapters, right-click your graphics card > Update driver.
- Choose Search automatically for updated driver software.
- Follow prompts to update, then restart your PC.
Alternatively, visit your GPU manufacturer’s website (NVIDIA, AMD, Intel) to download and install the latest drivers manually.
Step 5: Disable Antivirus or Firewall Temporarily
Sometimes security software mistakenly blocks applications, causing error codes like ERROR_26.
Before proceeding, ensure you’re not exposing your system to threats. Only disable antivirus/firewall temporarily to troubleshoot.
- Right-click your antivirus icon in the taskbar and look for a disable option.
- For Windows Firewall:
- Search Windows Security in Start.
- Click Firewall & network protection.
- Select your active network and toggle off Windows Defender Firewall temporarily.
Try running the app again. If it works, add the program to your antivirus/firewall exceptions.
Step 6: Perform a System File Check (SFC) Scan
Corrupt Windows system files can cause unexpected errors, including ERROR_26. Running an SFC scan repairs corrupted files.
How to perform SFC scan:
- Press Windows key + S, type cmd.
- Right-click Command Prompt and select Run as administrator.
- In the command window, type:
sfc /scannow - Press Enter and wait for the scan to complete.
- If issues are found, the tool will attempt repairs automatically.
- Restart your PC and test the application.
Step 7: Reinstall the Application or Game
If none of the above steps worked, your installation might be too damaged to repair.
How to reinstall:
- Open Settings > Apps > Find the app/game > Click Uninstall.
- Confirm removal and restart your computer.
- Reinstall the app from the original source (official website, Steam, etc.).
- Launch and check if ERROR_26 is resolved.
Bonus Tip: Check for Windows Updates
Microsoft frequently releases updates that fix bugs and improve system stability.
How to check for updates:
- Go to Settings > Update & Security > Windows Update > Click Check for updates.
- Install any pending updates, restart, and try again.
