Deleting previous versions of Photoshop when running an upgrade version

I am running an upgrade version of Photoshop CS. The full version I have goes back to Photoshop 5. I have installed on my machine Photoshop 5, Photoshop 6, Photoshop 7. Can I delete these previous versions as they are taking up space on my hard drive, and if I do delete them will my upgrade version of CS still work once these are deleted? And, how do I delete them safely, through Add/Remove programs in Control Panel in Windows?

Cathy,

Yes, delete from C/Panel > Add/Remove programs, but say 'No' to deleting shared files

I'd keep PS7 active if I were you. You never know when it might come in handy to have some form of backup!

I concur. Even though CS 2 for the most part blows me away, there are times when it doesn't quite act the way it's supposed to, making that copy of PS7 is invaluable.

Killing former incarnations is safely.
