I have MS Office 2003 (only Word, Excel, Power Point).
I have MS Office 2007 (only Excel).
I have MS Office 2013 (complete including Outlook).
I am using Windows 7 on I3 processor.
I want all these installations simultaneously because I have clients who want support in all these versions. I want to keep my copy (2013) as default. How do I install these packages (what order and settings) so that I keep one (2013) as default, and others still available in support.
