You can have one of two configuration types with regards to Office 2007 and 2003. There is a registry level change required to run them efficiently concurrently, which apparently creates separate instances of the offending dlls that otherwise conflict or something like that - definitely to run them seamlessly you need to edit the registry. Information is available from a variety of sources, (Woodys Office Watch is one who explored that ad infinitum as they sometimes do). Occasionally, as Christine has found you may not need to do that. The other option which I have done is have both versions of the software but I don't need to run them concurrently. I don't care about the Outlook overwrite if indeed that happened so have never checked; I only need either 2007 or 2003 programs. In fact I may have loaded just the relevant programmes I needed in any case. Don't remember. Anyway, you can run one or other version of 2003 or 2007 individually without problems on the one machine. Word does seem to work better at matching table and paragraph styles although the separate selection functions for tables and styles and formatting in 2007 is a difference. PowerPoint is a different beast.

Hi all I think in a recent (long-winded and somewhat ranty) thread someone mentioned being able to have Word 2003 installed at the same time as Word 2007 - is this correct or was I just dreaming (or brain reeling from slogging through the long-winded and ranty thread)? I'm modifying a previously 2007 Powerpoint slide pack for someone, and my 2003 graphics just don't match up. I'd like to have both versions on my machine at once, so I can learn the new stuff at my leisure. (I did actually snaffle a second machine for this stuff, but it's at home for my spare time - it would be much handier to have it all together in the one place. Assuming you could run the different versions concurrently and they didn't make little streamers of smoke come out the back of my machine. Or out of my ears.)
