I'd try recreating the droplet in photoshop cc and see if that works.
That didn't work for me as i'm still having the same problem.
Tried other fixes as well that were posted like running PS as adminstrator no luck
Adobe Photoshop CC 2014
I think it is worth noting through my observation of initalizing a droplet that you cant just stand alone run them (atleast that is the case for me)
My solution was as followed
To automatically have the droplet set to administrator
select droplet and right click > properties > compatibility > and check the box run as admin.
I also made sure that I allowed for firewalls to allow for droplets to be run.
control panel > system security > windows firewall > allow apps > change settings > allow another app > browse > select droplet > add
Drag and drop a file onto/into the droplet
If you want to remove the annoying security alerts each time you can do that in the user settings control but be warned it comes with consequences. scroll through the thread i believe another user discusses how that is done.
for that second part adding droplets you should just select your original droplet, I believe windows recognizes all droplets after that cause it shows up in the allowed apps as "Adobe Photoshop Droplets".
I also observed that they must be ran as the first operating procedure in photoshop. Meaning if you open any other documents before or prior to initalizing a droplet it will give you an communication error
In order for droplets to run outside admin the program seems to need a minimum of 512 ram, Apprently it utilizes photoshops 3d features.
