I was able to get the Canon Print Studio Pro plugin to work in Photoshop Element 13.
The current version of the install scrip for the Canon plug in does not recognize Photoshop elements 13 so the work around is to manually copy the plugins directly to the Photoshop Elements 13 plugin folder. Plugin file names are CNPSPP01.8li and CNPSPP02.8bf and are found in the canon print studio pro program files folder.
I will ask Canon tech support to update this script but it will no doubt take time.
