I am attempting to program a Jetstream JT270M using a Prolific cable.

The CHIRP Error message pop-up says

An error has occurred
could not open com4 (Error 2) The system can not find the file specified.

In the WIN10 Device manager listing for COM4 it says
Driver provide is prolific
Date is 10-17-2017
Version is

Device status is
This device cannot start. (Code 10)
A device which does not exist was specified.

Can anyone help me out with this?
