: Windows Defender frequently flags extraction routines as false positives, abruptly locking down the unarc.dll operations.
Windows Defender (or 3rd party AV) is likely scanning the compressed files as they are being unpacked, causing a timeout or blocking the write process.

Contrary to what the error implies, the downloaded files are rarely corrupted. Instead, error code 12 indicates a caused by system constraints, hardware instability, or software conflicts. Highly compressed game archives require significant RAM, virtual memory, and CPU cycles to extract. When your operating system cannot keep up with the demands of the decompression algorithm, the installer halts and throws this error. Technical Causes of Unarc.dll Error Code 12
Manually set the Page File to 1.5x or 2x your physical RAM size on your fastest SSD.

Highly compressed repacks push system hardware to extreme thresholds during extraction. Modern high-core processors and complex memory timings often cause decompression desynchronization or overheating, resulting in unarc.dll errors. 1. Downclock CPU State and Core Limits
By methodically working through this guide, from the simplest checks all the way to the more advanced system tweaks, you should be able to resolve the "unarc.dll returned an error code: -12" error and finally enjoy your game.
An interesting cause, specific to some unpackers, is the number of CPU cores. Some installation engines may become unstable on high-end CPUs with many cores (e.g., 16, 24, or 32 cores) or when Intel's Hyper-Threading is enabled. The parallel processing can cause race conditions and data corruption during the "surgery" of game repacks. Navigate to the tab in the new window
