I installed everything via the official creative cloud process and this function doesn't work for me. Not the hdr or the panorama merge! It worked perfectly in older versions.
I tried resetting the photoshop preferences file but it still doesn't work. Photoshop just starts and nothing happens when this feature is used within Lightroom.
When using the automate -> photomerge feature in Photoshop all works fine.
I use this feature in Lightroom a lot so please fix this!
The normal solution to fix PS not starting up after the upgrade to PS CC 2014, is to uninstall and reinstall PS CC 2014.
Photoshop is starting up just fine, but it just sits there and nothing happens.
I will uninstall and re-install Photoshop anyway just to try this.
After uninstalling Photoshop, restarting the pc and re-installing it the feature worked just fine.
