Hi Guys

am in poccession of my new office 2007 suite, am currently running 2002, do I need to completely uninstall 2002 first or can I just run 2007 install & it will overright as it installs?

this will go onto an XP Pro computer & then a Vista Home Premium......................
although am looking at upgrading to vista business or ultimate, with this again I'm not sure if I can just overright the old VHB with the new Bus or ULT version or whether I have to completely reformate the HDD first?

any help very gratefully received.

Pete
