Hello,
I having this issue as well... I have v1.0 of the Tool. The GUI start just fine, I'm able to load the SP and export the header file. I want to run the transparent mode RF test. But when I do Settings-->Select Port, there is no port selection popup.
I have followed the steps mention above. Set Java path to "C:\Program Files\Java\jre1.8.0_73\bin", copied the library files RXTXcomm.jar and rxtxSerial.dll
