Strike Technologies, the developers of AR2001-FP2001-FP04-FP04-AR Protection Relay, appear to be missing from the Internet, meaning that they don't have an active website to acquire the necessary information related to this device/software. Because of that, support is hardly a thing and operations like "password reset" are impossible to achieve.
If you still have the device/software, then I recommend reading its manual or user guide to see exactly what is the procedure to reset the password, if that's even available.
