i had to take my photoshop file into a hardrive because my dad was going to give me a new Mac and when things didn't work out and went back to my old one i use the time capsule thing to save everything before but didn't give me photoshop so i physically moved the file and tried to open it but then this error shows up

Please uninstall and reinstall the product.
