I would like to use NanoVnaSaver with my Vna, but the version 4 complains about missing DLL, and previous version does not even notice the VNA. I installed Python 3.8.10 but it did not help.
Beware of cheap underperforming clones
As of 2022 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.

Does NanoVnaSaver work with NanoVNA V2 plus4 with W7/32
I have the Nano VNA V2 but had the same issue, it looks like that nanovna saver is compiled for W10 only.
here there is a link for a W7 compiled version and other info
