I have used a meag328pb xplained board, no problem, on windows 7. I also have a xplained 3217 board, that doesn't show up (under tools). Somewhat foolishly, I initially plugged it in before I ran studio 7 (not sure if that makes a difference) & it started loading drivers. It looked like it was trying to install 4 drivers & one failed (I accidentally cleared the message, before I had a good look). If I plug in the 328pb board, it shows up & even shows a photo of the board in a studio tab. The other board shows nothing in studio & not listed in tools. However in the windows system tray, it shows I can eject it (safe to remove EDBG CMSIS-DAP), as it shows virtual comm port10. Thought I might "uninstall it" & try again, but not sure what needs uninstalled. Should the 3217 board show up as a photo in studio?
