Security Fixes
Use these notes if Windows Security, antivirus, or permissions block the client.
If Defender or antivirus blocks a file, restore it and add the game folder to exclusions.
Download only from the official links above to avoid modified or incomplete packages.
Do not mix old files with a new package. A clean folder patches faster.
If security software blocked a file, restart once and patch again.
