I have ESP32-32 board connected COM12 & can upload sketch with Arduino V2.0.0
I have 2 versions 1.8 & 2.0 Arduino on C drive (need 1.8 for another app, V200 is latest for win7)
I can see & select serial ports ok in the board selector.
Board type list is empty.
On the Offline PC I updated DotNet from 4.7.0 to 4.8.0, I tried to apply update 4.8.1 but it is blocked (wont install)
no change but some different values in the error report log.
I tried also on my E6440 laptop(win7px64) that already had DotNet 4.8.0 & same issue.
I tried used Arduini-cli V0.35.2 , I can run it ok by cmd & b4r board selector works.
I expect some possible issues later on being a pre release version of Arduino-cli.
I might have a go at building with "go-legacy-win7", I don't expect a result soon tho.
I did a build of latest Arduino-cli with go-legacy-win7, the board selector is working as expected.
At some time later I can test more of cli only within the scope (board selector, upload, ...) of what I am doing.
It is pretty straight forward to build, took longer to get the go paths right & download all the dependencies (my internet is just kbps in this wet weather)
