I am using Windows 10. I have installed the Cypress driver and it shows up under Device Manager as COM8. I have downloaded NanoVNA-QT-20200507.zip and unzipped it to a folder on my desktop. When I plug the S-A-A-2 into a USB port on my computer and turn the S-A-A-2 on, I hear the Windows sound that indicates the device has been recognized and is ready. However, nothing else happens, and I don't know what to do to get nanovna-qt to start on my computer. What am I not doing or doing wrong? Thanks.

I have tried repeatedly to use QT with my SAA-2N. My repeated results
totally replicate your's. I have given up using QT or any PC support app
with the unit. However, it is a wonderful stand-alone instrument. Yes, my
cables are good and work on other units. Also running Win 10 / 32 or 64.

That is interesting. I have tried some additional steps, but no luck. I really would like to be able to use QT. I wonder if it works correctly with a linux computer?
