Have installed Elements 12 - previously had version 10. All images copies across OK as did tags and previous people tagged. But now have lots of new images in Elements 12 that will not respond to the Add People. It prepares the files, searches for a missing file. When located I try to reconnect it as suggested. Do that - nothing seems happen. Then I get the message. 'People recognition supports photos only. Your selection includes invalid items which will be skipped. 'Fair enough - though why that is the case I don't know. But then I can't seem to get to the next stage where the program identifies shots with people who are untagged. Any help would be much appreciated.
In the Organizer, go to the Preferences (under the Edit menu on a PC) and ensure that all of the options are turned on for the Media Auto Analyzer.
I'm not sure why you're seeing so many missing files. Did you recently upgrade your software, move to a new computer or move your media files?
What operating system are you using, by the way?
