Upgrading Photoshop doesn’t require a previous installation
There’s an eternal misconception that if you buy an upgrade to Photoshop (or other Adobe software) and get a new computer, you must first install your older version(s) before installing the new upgrade. That’s not necessary. The upgrade will look for a valid previous installation, but that’s just a convenience feature meant to spare you having to type in your old serial number alongside your new one.
One other tip, as long as I’m boring you with minutiae: You can paste your serial number into the installer. That might not be obvious as the serial number field is comprised of several small text fields, but the installer is smart enough to spread digits across the fields when pasted. Therefore when getting a new version, I take a moment to type the serial first into a text document, after which I copy it & paste it into the installer. The extra steps may be worthwhile later in case you need to re-install, etc.
