In general，the reason for this error is that the windows system compatible problem.
This problem will not occur if you install FVDI 2019 or FVDI 2020 software in win10 64bit professional.
The main reason for this error is that the USB driver version is too lower. By default, v2.12.28 version driver will be installed in the system, but this version driver cannot be successfully installed due to system reasons.
