I'm using the trial version of Photoshop CC. Ran into quite a few problems, the latest of which has to do with the extension manager. I was not sure if it is not supposed to work in the trial version, or if it should be working, and I need to figure out what's going on. Thank you so much!
NEXT TIME I POST, I SHALL GLUE IT TO PAGE 1! Seems that everyone ignores easy questions!
Yes, Extension Manager can work with trial version Photoshop.
Note that Extension Manager CC wasn't installed along with Photoshop CC automatically. You have to download and install Extension Manager CC from http://www.adobe.com/exchange/em_download/. Then download and install the latest 7.1 update from http://www.adobe.com/downloads/updates.html. You can also use Creative Cloud application to install and update it.
