FitGirl uses (LZMA, ZTool, etc.) to keep file sizes tiny. This puts extreme stress on your CPU and RAM. If your hardware fluctuates for even a millisecond, or a background app tries to "read" a file while it's being unpacked, the decompression sequence breaks, triggering Error 14.

Antivirus software is the #1 cause of Error 14. It "locks" files while scanning them, preventing the installer from writing data. Turn off in Windows Security. Add the installation folder to your Exclusion list .
