I have been using a standalone atprogram for a while. It's from a 6.2 Studio and the USB drivers:
  from http://ww1.microchip.com/downloa...
  from https://www.microchip.com/mplab/...

It looks that I need to upgrade it because I need it to work with the new chips and UPDI.
- Will the newer atprogram work with the old (driver-atmel-bundle-7.0.888.exe) driver?
- Is there is way to install a new driver bundle without installing the Studio?

Atmel-ICE and AVRISP mkII.
Atmel-ICE currently only for SAMDs. And now I plan to use them for the 0-series too.
AVRISP mkII for other AVRs (I have a bunch of them, I really like them much better than Atmel-ICE, and I want to keep using them)

 

Edit: That is weird. I thought I saw a reply and was replying to the reply. Now I don't see what I replied to.

OK, installed the latest Studio (7.0.1931).
Copied stuff per https://microchip.secure.force.c...
Trying to run atprogram. It says:
[ERROR] Could not find atbackend.exe

The above web page says "Go to Command prompt browse the atbackend folder". Do I really have to? The old version worked without that.

"Set a PATH" - I'll if I don't find a better way. It's just annoying that the whole atprogram setup is so over-complicated. And earlier versions worked just fine without messing with the PATH.

OK, besides the path, everything else seems to work.
The drivers are at: https://gallery.microchip.com/pa...
There is a zip file there that includes the following:
      driver-atmel-installer-x64-7.0.1645.msi
      driver-libusb0-installer-x64-7.0.1645.msi
      driver-mplabcomm-installer-7.0.1645.exe
      driver-segger-installer-x64-7.0.1645.msi
      driver-winusb-installer-7.0.1645.msi
At first I installed all of them except mplabcomm. AVRISP mkII showed up in Device Manager under Atmel. But atprogram didn't see it. I almost gave up and was about to post more questions here. Then decided to install the mplabcomm too. That was it!

 

Anybody knows what that mplabcomm thing is? I also see that unlike the other 4 it doesn't even show in the list of installed products under Programs and Features?

It's the USB stack from MPLAB... The name is pretty revealing..
.
It handles the WinUSB (former Jungo) devices.

If mplabcomm handles the WinUSB, what does driver-winusb-installer-7.0.1645.msi (Atmel WinUSB) do?

It binds the devices to WinUSB (inf + DifX).

Apparently there is also a command line option:  -ab --atbackend <arg>      Specify path to atbackend executable.
