Can’t get FlexControl to install again after SmartSDR upgrade to v1.4.3.  (Didn’t get it to work in v1.4.0 either.) Remember having a problem with com port assignment conflict in an earlier version and was eventually able to change to 99, but now FlexControl doesn’t even show up as a COM device or port in Device Manager at all. 

Have removed all instances of SmartSDR, CAT, DAX and FlexVSP installations and reinstalled SmartSDR v1.4.3 a couple of times, each without getting FlexControl to install.  FlexRadio instructions on “How to change Com Port Assignment for a FlexControl” not of use for me because the “FlexControl USB Control Knob (Comxx)” device described is not even seen in Device Manager for me.  Only Com Ports shown are FlexRadio Virtual Serial Port (COM14) and FlexRadio Virtual Serial Port (COM4), and neither of these will show the “Advanced” Properties option described to change their Port Settings.  Have tried using each of my available USB ports.

Radio=Flex6700 PC=Surface Pro3 OS=Windows 8.1 (All updates installed.)

I don’t recall how this port issues was resolved in the past so need some help in getting the FlexControl to install.  What am I missing?
