I installed the windows 10 upgrade and since then Photoshop closes everytime I open it. I have tried to update CC. Photoshop CS6 (an old copy I still have access to) appears to work okay. What can I do to get CC 2015 working again? Will I need to uninstall fully and install a fresh? I don't want to unintsall if I can help it. It's bad enough that installing Windows 10 has caused this. Anyone got any ideas as my Lightroom 2015 works okay?
