| Cause | Likelihood | Explanation | |-------|------------|-------------| | | Very High | The .bin or .exe file was incomplete or altered during download (especially over Wi-Fi or unstable connections). | | RAM instability | High | Faulty or overheated RAM corrupts data during decompression. DDR4/DDR5 with XMP enabled is a common culprit. | | Insufficient disk space | Medium | The unpacked game is larger than the repack suggests. Error 11 can masquerade as a CRC issue when space runs out mid-extraction. | | Antivirus interference | Medium | Real-time scanning of the setup.exe or .bin files can modify or lock data streams, breaking CRC checks. | | Windows Defender Controlled Folder Access | Medium | Blocks the repack from writing to protected folders (Documents, Desktop, etc.), causing partial writes and CRC mismatch. | | Faulty storage drive | Low | Bad sectors on HDD or failing SSD can cause read/write errors that mimic corruption. | | Wrong extraction tool | Low | Using WinRAR or 7-Zip on the setup.exe itself (instead of running the exe) often yields error 11. |
