Should I delete version 5.5 afterwards? If Yes, do I do this thru the uninstaller in win 7?
My advice would be that, if you really don't want to keep 5.5, uninstall it BEFORE you install CS6.
The CS6 uninstaller and/or the CSClean script, if you end up having to use it, may uninstall some common files, often labeled the same, which may be needed by CS6.
