Using the laptop running Windows 7 it upgraded the camera to version 2.00, but not without some heart stopping moments. I followed the instructions, obtained from the Sony US website, exactly to the letter and it was not as they show. I had to leave the camera attached for much longer than the instructions said, make some guesses and finally I was forced to turn it off. When I disconnected the camera and turned it back on, it had updated OK. How I am not sure.
I have never had problems in the past when updating my other cameras, although the update process has always been somewhat stressful. Sony software is a pain in the butt.
I was unable to update the GPS Assist Data for my A77, using Windows 10.
