OM5P-AN router - NPF Error

[rich2202]

I am trying to use the FRC configuration utility (FRC_Radio_Configuration_16_2) to load the firmware onto the radio (OM5P-AN router). On multiple computers, I launch the program, select the Ethernet port, and hit the "Load Firmware" button. I then get the error:

Bridge firmware load field. Error finding NPF device name for adapter: Realtek PCIe FE Family Controller #2
Please reset the bridge and try again

Any idea what is wrong?

I ran as administrator
Disabled the wifi adapter
enabled sharing on the adapter
set the ip address to dynamic
disabled antivirus
