Title says it all.
I performed an upgrade from AS 7.0.634 to 7.0.790 and existing projects that I tried to load failed with "The project "proj_name" contains a device 'AT32UC3A3256' which is not supported by Atmel Studio. Please select another device.".
Headed back to the AS7 product page and checked that the UC3A3256 et al _is_ supported (I would have had a hard time believing that they skipped the UC3, though).
FWIW, VS2015 is on the same machine.
I have downloaded the complete offline installer, ~825 MB just to be sure, but no difference.
Where did I go wrong ?
Edit: I attached a log file from the VS output window after opening an existing project.
I see a lot of "Runtime.InteropServices.COMException" exceptions, so maybe my installation is broken...
