Good day to all in this forum,
I did download the v 0.5.4 64 bit version on my windows_10 PC.
When I launch the .EXE file I get the black background window and then the program starts.  The device port is displayed  but when I press the CONNECT  button I get a message and the program locks up.
I did try the 0.5.3 32 bit and it is working well.
How could I overcome the problem please ?
Thanks for all .
regards,
iw2fvo, Ambrogio

Ambrogio,



Nano VNA Saver application is created by a chain of amateurs, so there could be errors in any of releases.

The contributor for latest release 0.5.4 was zarath ( Hilger Muller ).

You can find on site github.com/NanoVNA-Saver/nanovna-saver/release/tag/v0.5.4 a remark: windows build seems to have trouble, don’t know if working as lacking windows…

Perhaps, they will find a fix for 64-bit version.



Regards,



Raphael

thanks a lot Raphael for the advise.All the best:iw2fvo, Ambrogio

I am unable to get NanoVNA Saver working on my Win 11 PC.  I started off with v0.5.4 (64 bit) with no success and then I read these posts.  So, I tried v0.5.3 (32 bit) and still no success.  In both cases VNA Saver was not finding my Nano VNA V2 Plus 4.  I clicked on Rescan but no result.  I clicked on Manage and a message appeared in the console screen: "NanoVNASaver.Controls.SerialControl -ERROR - Tried to open None and failed: 'NoneType' object has no attribute 'open'  ".
In Device Manager, under USB Controllers, I get a device showing as "Unknown USB Device (Device Descriptor Request Failed)
I tried installing Cypress USB Serial Driver but this made no difference.
Any help will be much appreciated, thanks.

Russ,



Based on my experience with VNA Saver v0.5.4 app, it is unreliable under Windows 10 and 11.

I gave up using this app and started of using NanoVNA – APP v1.209 under Windows 11 ( 64-bit ) and before with Windows 10 (64-bit ). It works reliably.

There is no need to change windows driver by Microsoft v10.0.22621.1194 with Cypress USB driver.



Regards,



RW

Russ,



I am sorry by misleading you… The recommended VNA-APP software V 1.1.209 by One of Eleven is good for NANO VNA V2 Plus 4 only when the firmware/software on your device is modified accordingly. My device is different model NANO VNA H4 and I experienced the same problem while I have been using SAVE v0.5.4.

Raphael,
Thank you for taking the trouble to explain all of this.  I will take a look at One of Eleven.
Kind regards,
Russ

I am still having no luck getting my Windows 11 machine to recognise my Nano VNA V2 Plus 4.   I have tried Nano VNA Saver,  VNA QT  (with the Cypress driver) and now VNA-APP software V 1.1.209 by One of Eleven.
In every case my Nano VNA is not recognised by my machine.  In Device Manager, under USB Controllers, a message appears "Unknown USB Device (Device descriptor request failed)."
My Nano VNA reports itself as v.29220301.
Please can someone help me with this?  Thanks, Russ

Russ,

Just checked with NanoVNA Saver 0.5.5 64-bit on Windows-11 Home and it
recognises my V2 plus 4 correctly.

Firmware is 20220814, I thought that was the latest?

Cheers,
David

Hello Russ
I do not have a Windows 11 machine so I can't provide a direct solution.
The VNA software will not work until the device is recognised by the
O/S (of course).
Using Device Manager as your arbiter is the first step.
My Windows 10 machines use a Microsoft USB-serial 'driver' from 2006
(usbser.sys)
Version 10.0.19041.2130. (I don't recall now if there was difficulty
at the beginning)
My linux machines use a built-in usb-to-serial interface that I've
never bothered to characterise,

So.
>From a hardware compatibility perspective have you tried these actions?
Possible cable fault: Use a different USB cable.
Possible computer hardware fault or incompatibility: Try a different port.
If you have both USB3 (blue) and USB2 (not blue); Try the alternative.
Try a machine with a Windows 10 O/S : Phone a friend?
Try a machine with a (recent) Linux O/S (driver built-in): Phone another friend?

Device issues:
Does the VNA charge/power-up with USB cable attached?

Should none of these trials succeed then it has to be said that you
could have a faulty device.

David,

Thank you for your generous support! I very much appreciate your thoughts.

I agree that your firmware is the latest. Mine is 5 months behind (I see that I miss-keyed the number on the forum.  I should have said V.20220301).

I have tried a different cable and different PC BUT not a USB2 port - will do that.

The VNA does charge and power up with a USB cable attached.

I shall now try to update my firmware from a linux device. Time to get out that old Raspberry Pi.

If I achieve success I will be sure to tell you.
Very best wishes,
Russ, G4SAQ

Russ,

I discovered that my driver (working under Windows-11) was from Cypress.
