Hi. I was able to get the above DISM to work and went through the process but I still cannot open files with out the error "element not found." I'm not real computer savvy but I can follow directions. lol. Can you help?
With "files", are you referring to pictures? If yes, check out this post:

It also says your error is for other things too. Try the steps which you have never performed before.
