There are a few things to think about before installing the Office 2007 suite. Do you want to upgrade an existing version of Office or do you want to start fresh, by installing a clean version of Microsoft Office and erase any and all previous editions? Perhaps you want to do both; maybe you want to keep your old version of Microsoft Office just the way it is, while at the same time installing a clean, fresh copy of Microsoft Office 2007. Any of these solutions are options.
If you aren’t sure what the difference is between an upgrade and a clean installation, read on. An upgrade builds on the version of Microsoft Office you already have, and thus protects personal settings for AutoComplete and AutoRecover, margins, changes you’ve made to the dictionary, colors and backgrounds, rulers, page layouts, and more. Before you skip forward thinking that this is a perfect solution, an upgrade will also preserve the problems you’ve been dealing with– or those you’ve created. If you want to see Office2007 in its untainted form, perform a clean installation.
You can install a new copy of Office while keeping your existing Office suite applications in one piece. You should choose this option if you’ve never used Office 2007 before and aren’t sure if you’ll like it. This won’t work for Outlook 2007 though, your older version of Outlook will be upgraded no matter what.
