[Making a copy of OfficeXP pro from only the \Program Files?]

Does anybody know how to make a useful copy of Office xp pro from only the \Program Files copy? The PC has issues (needs larger drive & more memory) & I'd like to copy office to be useful from the confines of a new hard drive.
Or better yet, if I clone the present hard drive using Acronis 11 - how do i clean out the junk from the installed programs so only XP Pro & Office Pro are cleanly installed?

 

Clean the disk first: Use Add-Remove Programs in Control Panel Where possible; otherwise delete appropriate folders with theis contents. Then make your Acromis image on extermal media.
