long ago and far away i purchased a copy of Adobe Photoshop 7 [not Photoshop Elements 7!]. i have both Photoshop 6 and 7 on my computer. does Photoshop 7 need Photoshop 6 to operate or can i eliminate it?
They are independent, you can remove version 6 and version 7 will continue to work. (Unless something wrong happens during uninstall, in that case you may need to repair or reinstall version 7, but this should not happen.)
