1. Understand the Problem
The error typically appears when launching World of Warcraft and may display a message such as:
“The application was unable to start correctly (0xc000007b). Click OK to close the application.”
This can indicate several underlying causes, including:
- Corrupted or missing system DLL files
- Conflicts with third-party applications
- Outdated graphics or system drivers
- Corrupted game files
2. Run WoW as Administrator
Sometimes, lack of proper permissions can cause the game executable to fail. Here’s how to run WoW with elevated rights:
- Navigate to your WoW installation directory (usually in the Program Files folder).
- Right-click on WoW64.exe.
- Select Properties, then navigate to the Compatibility tab.
- Check the box that says Run this program as an administrator.
- Click Apply and then OK.
3. Repair Game Files Using Battle.net
The Blizzard Battle.net client includes a built-in function to scan and repair game files. This can resolve issues caused by file corruption:
- Open the Battle.net desktop app.
- Select World of Warcraft from your games list.
- Click the Options menu (Gear icon).
- Select Scan and Repair.
- Click Begin Scan.
Wait for the tool to complete the scan. It will automatically fix or re-download any damaged or missing files.
4. Update Your Graphics Drivers
Outdated or corrupted graphics drivers can cause application errors. Keeping your drivers updated ensures compatibility and better performance.
- For NVIDIA users: Visit the NVIDIA Driver Download page.
- For AMD users: Visit the AMD Drivers and Support page.
Download and install the latest drivers for your graphics card, reboot your PC, and try launching the game again.
5. Reinstall Microsoft Visual C++ Redistributables
WoW relies on certain Microsoft components to function correctly. Missing or corrupted Visual C++ libraries often cause startup issues.
To reinstall:
- Open Settings > Apps and uninstall all instances of Microsoft Visual C++ Redistributable.
- Visit the Microsoft Visual C++ Redistributables download page.
- Download and install both the x64 and x86 versions.
- Restart your computer after installation completes.
6. Check for System File Corruption
Corrupt or missing system files can interfere with WoW’s operation. Use the built-in System File Checker tool to identify and repair these files:
- Press Windows + X, then select Command Prompt (Admin) or Windows PowerShell (Admin).
- Type the following command and press Enter:
- Wait while the system scans. If issues are found, Windows will attempt to fix them automatically.
sfc /scannow
7. Disable Background Applications
Conflicting software can prevent WoW from launching correctly. Temporarily disable third-party apps such as:
- Antivirus or firewall software
- Overclocking tools (e.g., MSI Afterburner)
- Game boosters or overlays (e.g., Discord, NVIDIA GeForce Experience)
After disabling these, reboot and launch WoW again to see if the error is resolved.
8. Reinstall World of Warcraft
If none of the above steps solve the problem, a clean reinstallation of WoW may be required. This ensures all corrupted files and conflicting settings are removed.
- Open the Battle.net app and uninstall World of Warcraft.
- Navigate to the installation directory and delete any remaining WoW folders.
- Reinstall the game from the Battle.net client.

The WoW64.exe Application Error is troublesome but usually fixable. By methodically applying the steps above, you can identify the root cause and restore your game. If none of these solutions work, consider reaching out to Blizzard Support or visiting technical forums for additional assistance.
