Photo booth kept saying I could't open it because of the version I was in so I stumbled upon this fix.
Drag photo booth off of your dock and you'll see the puff of smoke. Next, go to the macintosh HD and click applications. Then just drag photo booth from the list and put it onto your dock and it should work.
I don't know if it will work for everyone, but it worked for me.
