I have a new computer and want to reinstall Photoshop on the new computer. Is there a certain procedure I need to follow; or, do I just use the installation disc that I used on my original computer?
I don't really understand ... you wouldn't re-install on a new computer ... you would install, not re-install ... so I'm not sure what your concern really is.
Nevertheless, any installation or re-installation can be done from the installation disk.
I think the query is regarding licensing considerations i.e. do you have to uninstall from one computer before installing on another?
