Have you deactivated the program on your computer that you're no longer using? Transfer activation
If you are transferring an activated copy to a different or new computer, you can transfer the activation to the new computer. Go to the Help Menu of the application and choose Transfer Activation. You will need an internet connection to complete the activation transfer process. Upon completion of the activation transfer, your existing product installation will be rendered unusable, and you will be able to install and activate the copy on the new computer.
Have you been doing your install as an administrator on your machine? If you're trying to install it as a regular user, you probably don't have sufficient privileges for everything Photoshop needs to do.
Have you tried copying the install folder to the desktop and running it from the desktop (again, as an admin)?
