This software is considered incomplete and abandonware. It is missing the GCP files that accompany the .exe and is otherwise unusable. It's presented as-is and the safety of the executable is widely regarded as insecure and unknown. It's advised to run in a virtual machine or on a dedicated machine that doesn't contain critical or sensitive data.
