I'm a bit hesitant to install Office 2008. I've read a lot of problems/issues with the new version. Is it possible to run 2004 and 2008 side by side? Meaning I have the ability to choose which version I work off at any time. I'm assuming the 2008 installer will upgrade the 2004 version. I haven't tried the install yet, so don't know this for sure. If this is the case then how do you go about installing 2008 without upgrading 2004? Do I need a separate partition and then install 2008 there?
