Elements 7,10,11,12,13,14,15 - Photoshop CC 2017 - Lightroom CC 2015 Windows 7 Pro & Windows 10 Pro
I updated both Elements 14 and Photoshop CC this morning.
You know what? I have opened and closed PSE14 several times today without getting an 'updating' prompt and Help > Update showed everything ok. You made me doubt, and I just checked 'About Plugins'... and I am updated to 9.3 >:(. Next time...
