Droplets don't work. Every time I try to use a droplet I get the error message "droplet could not communicate with Photoshop". CC2014, CC and PS 5 on a new computer with Windows 7. I found older reports that this issue has been solved but the solution didn't work for me.
I could solve this problem by re-installing CC2014. There's a big mess in the registry related to the settings of the Photoshop OLE Automation objects when multiple versions of PS are installed. My solution was to uninstall CS6 (I had already uninstalled CC), run CCleaner multiple times until it indicates no more issues in the registry (save your changes when running CCleaner) and then re-install CC2014.
