Unable to open Photoshop from back-up hard drive to transfer to new computer

[irenek47998690]

I have my Adobe Photoshop backed on a external hard drive. My 2011 MacBook Pro computer recently died and I bought a new 2015 MacBook Pro. I went to open my Photoshop Elements 10 from my external hard drive and it won't open. I get a code error: 6. I can not find my old CD which supposedly has the product registration number on it, but did find the original box and everything else it came with. How can I get my stored software open from my external hard drive? HELP!

Hi

You can download Photoshop Elements 10 from here

Download Photoshop Elements 13, 12, 11, 10, 9, 8, and 7

The issue is I can't find my registration number as it is on the sleeve of the CD that I have misplaced and I don't want to buy it again. I have everything else, original box, and everything in it (of course).  So, the question is can I somehow open the file on my back-up hard drive? Not sure what the code error: 6 is.

- page has links to programs to find an installed serial number in Mac or Windows

I do NOT know if the serial number finder will work on a backup drive
