The wow-64.exe application error will prevent you from being able to play World of Warcraft because your system is unable to run the game‘s files. Immediately you launch the WoW, it crashes with the following error pointing to the Wow-64.exe file.

Your computer can’t open World of Warcraft if the cached files are corrupt or the executable files are broken or blocked by a security feature. If you are currently experiencing this issue, you’ll find working methods to fix it and get your game back up and running.

How do I fix the Wow-64.exe application error?

1. Delete the Wow cache

  1. If the game is open, ensure to close it completely.
  2. Open the File Explorer and go to the installation folder of World of Warcraft (Program Files or Program Files  (x86) folder in the C:/ drive).
  3. Find the Cache folder and delete it.
  4. Launch World of Warcraft and see if this solution has cleared the wow-64.exe application error.

2. Temporarily disable your antivirus or exclude the Wow folder


Your antivirus software may be behind the wow-64.exe application error, as several occurrences have been investigated to be due to an antivirus tool blocking processes and executables from modifying the system files.

In troubleshooting the wow-64.exe application error, you have to disable your antivirus temporarily and retry the game. If you don’t get the wow-64.exe application error with the antivirus off, then you can be sure that you’ve found the solution.

However, you don’t want to run your computer without an active antivirus; so, I recommend that instead of entirely deactivating your antivirus, you can exclude the WoW folder from its checks.

The process of adding folders to exceptions differs quite a lot between antivirus software. Here are the steps required to do so efficiently for a few antivirus software options:
