| Problem | Solution | |--------|----------| | “Cannot find key” error | The PKG is encrypted with a unique title key. Use a different tool like pkg2zip or find the key online. Easy PKG Extractor 1.07 only handles system-encrypted PKGs. | | “Unsupported PKG type” | Some PS4 PKGs or very old PS1 classics use a different header. Try version 1.08 or pkg_decrypt . | | Crashes on large files | Run as administrator, disable antivirus temporarily (false positive risk), or extract in Safe Mode. | | No files extracted / zero bytes | Anti-virus quarantined the EXE. Restore it and add an exclusion folder. |
