Recently I installed MS Office 2010 as a separate installation(not upgrade) on my Windows Vista. I want to use both MS office 2007 and MS Office 2010.
But whenever I switch to Word 2007 from Word 2010 or vice-versa, a Configuration process starts which is like a setup of Word and it take lot of time.
Is there any way of using both Offices simultaneously?
