I had some problems getting my AVRISP MKII to work with AVR Studio 4.19. Here is my original thread:
I was finally able to get it working by installing driver-atmel-bundle-7.0.888.exe
I ended up not using the Win10 machine for over 6 months due to many problems, but most of them are now sorted out so I'm trying to set up 4.19 again.
Unfortunately, driver-atmel-bundle-7.0.888.exe does not seem to be available any more and due to all my problems I've lost the copy I had.
Can someone please tell me where to get it, or send it to me.
