Beware of cheap underperforming clones
As of 2023 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.
See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

software for NanoVNA V2 Plus 4 by joe smith
I first saw him on eevblog and at that time he was reluctant to share his work. His GUI app looks very attractive.
A few days ago I tried to run his software. It installed flawlessly, but when launched it complained about some missed LabView modules (about 10 consecutive dialogs about this). The application finally opened, but I was unable to even switch the COM port to connect to my V2+4, the app didn't respond.
Does anybody made it work in Win10? Do I need to have any previous LabView software in my box? The eevblog thread starts to be huge and is not so easy to find info there. Also, the author seemed a bit reluctant to share his work, so I do not want to pester him with my issues.
Thanks & regards.
My attempt has been on Win7, all OK except a "license request" for ActiveX
virtual driver (or similar).
The COM port is fixed on the default values and also clicking on "refresh"
non other ports appears
(the NanoVNA is on COM27 or COM28 depending on which USB connector I plug
No way to establish the link.

I installed it on a Win10 running within Parallels on OSX10.15.7, I also installed the Cypress driver.
Works perfectly, thanks joe.

Hi all! See my comment on the youtube video about this software.
You need to,install NI VISA. I contacted the author, He probably forget to
include this package.
It work well if you already have NI Labview on your computer, otherwise ,
you hve to install NI VISA, and you will see the com port windows with all
your com port available on your PC.Regards.
I think that the author will include the missing package soon.

Thanks, but I'm still unable to make it work. After installing NI VISA and re-installing Joe's software, when the application is launched nothing happens (no error messages, no window pops, nothing, nada).
A pity, as the software looks superb.
Thanks & regards.
I did not have to reinstal Joe's software.

Joe smith already added the NI VISA package to the new build that he uploaded to github.
Yes he added it yesterday, thanks.

Hmm, I looked at that page, I am not very good with software, I see 20 files of the same size and a smaller one plus 2 source code files. Do I have to dl all 20 and then somehow compile them or is one of them all I need to run on WIN-7.
Yes put all of them inside a folder and unzip the first one , it will
include all automatically for unpacking...
You will have a new folder with setup inside.

I must be dumb. I downloaded all the files into a folder called nanov2. and unzipped the one called nanoVNA_V2Plus-0.10.zip. It created new folder called NanoVNA_V2Plus-0.10 in which there are 4 files. I ran the file V2P4_Test_R0.exe and it just came up with an error message immediately about nor being able to find LAbview Runtime_engine. Teh files with numbers on seem to be unused and unchanged! What am I doing wrong? regards Mike
did you get the runtime version 2011 ? That's the version of LabVIEW used to package the executable.
So, must I understand that, apart from the software (the various zip files), I must install some other software (such "LABview runtime engine")?
I've installed both variants of Joe's software:
* The first one, not including NI-VISA
* The 2nd one, including it
But neither worked. Both showed ~10 error dialogs at start-up complaining about missing procedures/libraries... Then, when trying to connect to the nanoVNA, the first one didn't allow me to select a COM port, whereas the other allowed me, but the Link button did nothing.
Thanks & regards.
"did you get the runtime version 2011 ? That's the version of LabVIEW used to package the executable." I did yes.
Ok, thanks, so finally the mechanism to install it is:
* Download National Instruments LabVIEW runtime 2011 32 bit and install it (reboot required)
* Download the 21 .zip files from GitHub. Uncompress the first one (this uncompresses all 21) and launch the setup.exe (reboot required)
* Launch NanoVNA_r10\NanoVNA_V2plus ⇒ You did it!!
Thanks, I do have it working now. Regards.
The files are a spanned ZIP containing the runtime engine as well as NI-VISA. There should be no need to rename files or to download other files. I use 7-ZIP.
The software that is included with this spanned ZIP is fairly old. I ended up moving to a common code base and porting it over to the original hardware. There are now two branches, one for the V2 Plus, the other for the original hardware. Once you have the runtime and VISA installed, there is no need to reinstall them. Just download the software for your hardware and copy it to where ever you like. I strongly suggest reading the manual before you waste too much time trying to use it. It's nothing I would suggest a beginner attempt to use, rather stay with one of the many supported programs available.
This short video shows some of the latest changes.
Joe, Thanks for all your work on this software. Its great!
After a number of false starts, I finally got the install correct. Even after reading the manual, it was not at first clear to me how to correctly do the install. Also, I was not fimiliar with spanned zip.
Here is what worked:
Install 7-zip (free)
Download all 21 NanoVNA_V2Plus_Installer.zip. nnn files from here:
Open NanoVNA_V2Plus_Installer.zip.001 with 7-zip (all 21 installer zip files will then be extracted).
Run the installer. You will then have version 1 installed at C:\Program Files (x86)\NanoVNA_V2Plus
Confirm that it works, than get the latest version of the exe at:
Replace the version 1 NanoVNA_V2Plus.exe in C:\Program Files (x86)\NanoVNA_V2Plus
with new version exe.
I am still trying without success to get either the Solver32 or NanoVNA V2Plus software running properly. Solver64 works without any issues on the other hand (when installing the Runtime 2021 + VISA 21).
What happens with the Solver32 is that I get a bunch of errors as described above also with missing "sub" (pic is from NanoVNA, Solver32 gives even more errors).
The interfaces starts but it is not functional (i.e. trying to connect to the serial won't work).
I have tried installing the SW from the archive NanoVNA_V2Plus_Installer.zip ( https://github.com/joeqsmith/NanoVNA_Software/releases/tag/0.10 ) before or after installing the Runtime 2011, or without the runtime altogether. I tried upgrading the runtime with the Patch, I tried using Runtime 2011 SP1 (with or without the Patch). Always the same problem. Any hints what I could be doing wrong? One mention, I have windows 11.
