Troubleshoot Error #134 Fatal condition!

[KITZUNU]

This error may occur when World of Warcraft is prevented from making changes to a game file. It can be caused by incorrect permissions, a security program, or an error in the file itself. Follow the steps below to resolve the issue.

1. Run the WoW-Mania Launcher App in Administrator Mode to address many installations, patching, networking, and start-up errors.
2. Update or temporarily uninstall any security programs, which may mistakenly identify the login module as a security threat.
3. Update your drivers and operating system to resolve any compatibility issues.
4. If the problem persists, uninstall and reinstall the game.
