I have a need to install both MS Office 2003 and MS Office 2010 on 1 single PC.  Are there any issues with that ?   I use Windows 7 and I have plenty of RAM and disk space.  I would NOT need to have both applications open simultaneously.

    That will work but you can't have two versions of Outlook on a pc.  You can only have Outlook 2010 after you install it.  Other than that, you can run Excel, Word, Powerpoint from 2003 and 2010.  Install 2003 first.  Then when you install 2010, make sure to customize the install settings and tell the installer to keep the older versions of the programs installed instead of upgrading them.

    If you need to run both copies of Outlook, then I would recommend creating a virtual machine.  You can use Virtual PC from Microsoft (, VMWARE, or even VirtualBox (

    SMALL PROBLEM.......

    Your advice tells me to "Keep the older Versions".  But if I do that then I'll have 2 different versions of Outlook on my PC.....which you stated in your 1st sentence I can't do that.

    Outlook is the only one that will be upgraded (if you choose to keep the older versions).  Meaning, you would have all of the old versions, except for Outlook.
