Lightroom CC 2.2: HDR merge getting stuck at 100%

Hi Lewis, does this happen with all sets of images you try to merge? Or just a specific set? If a specific set, can you zip them up and post them for us to download and troubleshoot?

Same thing, version 2.3, no specific set of pictures, it happens mostly on all of my stacks.
In my case it is stuck on "Gathering Data... 100%".

I am sorry to hear that the 2.3 update didn't fix the issue for you. At this point, we would need to get a few sample files from you that fail so that we can test with your files. Are you willing to share files with us?

Any update? I have the same identical issue, with Lr CC 2.3. I cannot merge any AEB bracketing at the moment.

Kirill, 

I tested with your files (thank you for those) using Lightroom Desktop 2.3.  I was able to successfully merge an HDR, a Pano and an HDR/Pano from your files with no issues.

I would recommend you reset your preference file and try again.  If that doesn't cure it you may want to do a clean install of the App. 

Preference File reset:

A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences. 

Reset Procedure:

1. Close Lightroom.
2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom. 
3. Overwrite the Preferences when prompted by the dialog.
4. Close Lightroom.
5. Restart Lightroom.

Does the behavior continue after resetting the preferences?

Clean Install:

Close Lightroom
Restart the computer
Use the Adobe Creative Cloud App to uninstall Lightroom
Restart the computer
Install Lightroom  via the Creative Cloud App without launching any other programs.
Restart the computer
Launch Lightroom
Wait 5 minutes

I am going to post these same instructions into your other thread. 

Lightroom Desktop 2.4 was released today and contained a fix for this issue. Please update to 2.4 and verify that you are no longer seeing the issue. Thank you!
