Overwatch Error 0xe0070150: Fixes That Work

Overwatch error 0xe0070150 is a known game-launch failure that appears when the Battle.net client cannot verify or access the game’s files, often triggered by antivirus interference, corrupted game data, or an outdated GPU driver. This article explains the most common causes and provides step-by-step fixes to get you back in the match.

What Causes Error 0xe0070150?

Error 0xe0070150 typically occurs during the game’s startup sequence, before the main menu loads. The code itself is a generic “file access” error, meaning the game client is trying to read or write a file that is either missing, locked, or blocked. The most frequent triggers are:

• Antivirus or Windows Defender quarantining or blocking game files (especially after a patch).
• Corrupted game cache or incomplete update installation.
• Outdated or conflicting GPU drivers that cause the game to fail during initialization.
• Background applications (like Discord overlays or RGB software) interfering with the game’s file access.

Before You Start: Quick Checks

Try these simple steps first—they resolve a surprising number of cases:

1. Restart your PC and Battle.net client completely.
2. Run Battle.net as administrator (right-click the shortcut, select “Run as administrator”).
3. Check if your Windows OS is up to date (Settings > Update & Security > Windows Update).
4. Ensure your system meets Overwatch 2’s minimum requirements (Windows 10 64-bit, 8 GB RAM, etc.).

Fix 1: Whitelist Overwatch in Antivirus

Antivirus software often flags game executables during updates, causing error 0xe0070150. To fix this, add the Overwatch folder and Battle.net folder to your antivirus’s exclusion list.

1. Open your antivirus settings (for Windows Defender, go to Windows Security > Virus & threat protection > Manage settings > Exclusions).
2. Add the folder where Overwatch is installed (default: C:\Program Files\Overwatch).
3. Also add the Battle.net folder (default: C:\Program Files (x86)\Battle.net).
4. Restart Battle.net and try launching Overwatch again.

If you use third-party antivirus, refer to its documentation for adding exclusions. After whitelisting, run a quick repair of the game (see Fix 3) to restore any files that may have been removed.

Fix 2: Update GPU Drivers

Outdated or corrupted graphics drivers can cause the game to fail during startup, triggering this error. Update your drivers to the latest version from the manufacturer’s website (NVIDIA, AMD, or Intel). If you recently updated and the error appeared, try rolling back to the previous driver version.

• For NVIDIA: GeForce Experience or the NVIDIA website.
• For AMD: Adrenalin software or the AMD website.
• For Intel: Intel Driver & Support Assistant.

After updating, restart your PC and launch Overwatch. If the error persists, use Display Driver Uninstaller (DDU) in Safe Mode to completely remove old driver files before reinstalling the latest version.

Fix 3: Repair Game Files

Corrupted or missing game files are a common cause. Battle.net has a built-in repair tool:

1. Open Battle.net and select Overwatch.
2. Click the gear icon (Options) next to the “Play” button.
3. Choose “Scan and Repair”.
4. Wait for the process to complete (it may take several minutes).
5. Restart Battle.net and try launching the game.

If the repair doesn’t find any issues, you can also delete the Cache folder inside the Overwatch directory (default: C:\Program Files\Overwatch\Cache) and then restart the game. The game will rebuild the cache automatically.

Fix 4: Disable Background Overlays and Applications

Overlays from Discord, NVIDIA GeForce Experience, MSI Afterburner, or RGB software can interfere with Overwatch’s file access. Temporarily disable them:

• Discord: Settings > Overlay > Disable.
• NVIDIA GeForce Experience: Settings > General > In-Game Overlay off.
• MSI Afterburner/RivaTuner: Close the application entirely.

Also close any other non-essential background programs (browsers, chat apps) before launching Overwatch. If the error disappears, you’ve found the culprit—you can re-enable overlays one by one to identify which one causes the problem.

Fix 5: Clear Battle.net Cache

The Battle.net client itself can have corrupted cache files that prevent the game from launching. Clearing them is safe and often resolves launch errors.

1. Close Battle.net completely (check system tray for the icon, right-click and select “Exit”).
2. Press Windows + R, type %ProgramData% and press Enter.
3. Delete the Battle.net folder (this is safe; the client will recreate it).
4. Press Windows + R, type %AppData% and press Enter.
5. Delete the Battle.net folder (in the Roaming folder).
6. Restart Battle.net and try launching Overwatch.

Frequently Asked Questions

Does error 0xe0070150 mean my account is banned?

No. This error is a file-access issue, not a ban. Bans typically show a different message related to account status. Error 0xe0070150 is technical and fixable with the steps above.

Will reinstalling Overwatch fix the error?

Reinstalling can fix the error if the problem is deeply corrupted game files that the repair tool doesn’t catch. However, it’s a last resort because it’s time-consuming. Try the repair tool and cache clearing first.

Why does the error appear after a game update?

Updates can sometimes leave temporary files that conflict with the new version, or antivirus may flag the new executable. Running the repair tool and whitelisting the game folder usually resolves this.

Can this error be caused by overclocking my GPU or CPU?

Yes, unstable overclocks can cause the game to crash during startup, and the error code may appear. Reset your GPU/CPU to stock clocks and test. If the error disappears, your overclock is unstable for this game.

Is there a way to prevent this error in the future?

Keep your GPU drivers and Windows updated, maintain a stable overclock (or none), and keep Overwatch and Battle.net whitelisted in your antivirus. Also, avoid closing the game during updates, as that can corrupt files.

When to Contact Support

If you’ve tried all the fixes above and the error persists, it may be a deeper system issue. Contact Blizzard Support with your system specs, the exact error code, and a list of steps you’ve already tried. They can provide further diagnostics, such as checking for corrupted Windows system files (run sfc /scannow in Command Prompt as admin).

Remember, error 0xe0070150 is almost always fixable with patience. Start with the simplest fixes (antivirus whitelist, driver update) and work your way down the list. Most players resolve it within an hour.
