I have an Illustrator extension I built using HTML5 in Extension Builder 3 with Eclipse on Windows. I followed the instructions here: Adobe Extension Builder and Creative Cloud 2014 to update it to CC 2014. When I install the new extension in Extension Manager it appears in the Extensions list but nothing is unpacked into the C:\Users\<username>\AppData\Roaming\Adobe\CEP\extensions folder so it therefore doesn't show up in Illustrator CC 2014 either.
I have checked the Extension manager logs and don't see any obvious errors. Anyone else seeing this issue and have a solution?
