THANK YOU SO SO MUCH FOR ANYBODY THAT CAN HELP OR EVEN IF YOU CANT THANK YOU ANYWAY
After the installation is done:

* Search > amtlib.dll
* Extract amtlib.dll from the disc and copy.

(If you want, you can backup the original amtlib.dll files, but I personally didn't. It still worked fine for me, but do it anyways if you don't feel confident enough.)

* Starting from the top (right click > open file location > paste.)

(REPLACE ALL 15 FILES.)

* Open up Adobe Photoshop
* Start up the Keygen
* Generate Serial > copy Windows/Mac Serial then paste it in the setup.
