Tonight NanoVNA Saver started crashing a few seconds after I connect to the first gen NanoVNA I've been using for a long time. The program finds the serial port, and is stable until I connect. It says connected, then the window closes a few seconds later. This is happening with the latest 0.5.2. The Nano is working fine stand-alone. This is on a Windows 10 PC.
Any thoughts?

I just downloaded SAVER 0.5.2 and it is working fine with my Win10 (10 yr old) desktop.

I do not see a whole lot of changes compared to earlier SAVER versions in terms of measuring common antenna characteristics via the S11.

I just gave a talk on Nano VNA to a county ARES group (near Philly) and it was working fine on my setup.
I used it to show:
Reflection coefficient, Return Loss, SWR, Phase, R and X, Z, and of course Smith Chart

Everything worked well with great graphs in bold colors.

It is SO much easier (for me) to use the Nano VNA (mine is 3 yr old now) with SAVER software that to use it as a stand-alone instrument.

So perhaps there is something unique to your setup/config that is failing.

COM port issues?
Cable RFI?

0.5.2 is buggy. Wait for 0.5.3



I am testing fixes daily as the developers sort out the problems.
(Linux here but I'm sure these issues also apply to Windows)

The first thing I would try is to use a new USB cable. They do wear out.
And Saver, as good as it is, does not do very good error checking on
returned data from the nano - it wxpects it to be well-behaved, so if a bad
cable causes data issues, it can crash saver.

Why don't you go back to an earlier version. What does not work is to use a recent version on an old OS. I don't think it affects the drivers (what do the experts say?). Personally I went from 0.3.8 which worked under Seven to 0.3.10 which did not work under Seven. But a nice OM gave me, here, a recompilation of 0.3.10-Win7 for Seven.
