A link was provided to a new ZWO driver package:
ZWO_ASI_Cameras_driver_Setup_ARM64_V3.22.0.06122.exe
This was installed in the Win11 running on VMware Fusion, on Mac M4.
The Device Manager now showed a new option for device drivers, ARM64.
The first time I tried to update the driver for the usb zwo120, it failed again due to the Authenticode block. That was turned off, (shift-restart, troubleshoot, advanced options, startup settings, #7).
The update driver then worked!!! The ZWO120mini camera now shows up in Device Manager as an imaging device.
Thanks for all the support.
