Error when creating panorama in elements 14.

Great.  I created copies of all the files, reloaded the copies and it worked fine.  Thank you for the help.

There is a bug in PSE14 with this error message. It means that the panorama plugin does not handle properly the way vertical and horizontal images are coded in the file format. Either the orientation is 'baked in' the frame of pixels, or, more frequently, simply indicated as a tag in the exif metadata. With this message, you have to open and save your files as copies to be able to perform the merging of images. There were other isues with panoramas in PSE14. My advice is to start the panorama from the organizer rather than from the editor (in guided edit).

Michel,

Thank you for the reply, that answers my 16 bit file question.  Any thoughts on why I am getting the error "Documents must be saved before they can be merged" when attempting a panorama using 8 bit jpeg files?  Thank you.

The reason is that creating panoramas implies using layers and masks, and Elements does not support layers in 16-bits mode. You'll need the full Photoshop.
