A search of this forum reveals a number of people experiencing issues with merging in 2015.2 and 2015.2.1, without any posted resolutions:
I recommend that you do as many, many others have done and revert back to 2015.1.1, the last stable release: http://www.lightroomqueen.com/how-do-i-roll-back-to-lightroom-2015-1-1-or-lightroom-6-1-1/ Wait until Adobe cleans up the mess and releases 2015.3, and let others do the beta testing.
Windows 7 Home Premium, SP 1.
I must stress that the panorama merge feature worked perfectly before I updated LR...
Thanks John, I am leaning that way myself... What a nuisance
I am sorry for the inconvenience caused to you.
Please follow the below link to roll back to Lightroom 2015.1.1(Lightroom 6.1.1)
Refer to this document on how to roll back to Lightroom 6.1.1 (Instructions to roll back to a prior update version)
I'm having the same trouble too. you can click on HDR or Panorama merger and nothing happens. I use a Mac book Pro and run Yosemite OS. Does anyone no how do remedy this issue?
What version of LR are you using? 2015.3 or 6.3 are the current versions.
I'm having the same trouble too. Create HDR or Panorama merger fail.
I use a ASUS Zenbook and run it on Windows 8.1 with last updates.
