I installed AS7.0.2389 on a Win10-64 DeskTop PC.
I can't find any Release Notes.
Snap is recognised.
Both Snap and Pickit4 have a "Communication mode" setting but Set AVR always fails.
If you select Device Programming for Pickit4 AVR and ARM devices are available in the dropdown.
It prompts for AVR mode if necessary. AVR mode succeeds ! Programming works.
If you select Device Programming for Snap no AVR or ARM chips are available in dropdown. Manually typing ATmega328P also fails.
Snap is recognised by MPLABX-IDE. It programs and debugs AVRs. So it must be in the correct mode.
