Can I install MS Office 2003 and 2007 side-by-side on Windows 7?

Glencam53 March 26, 2014

My operating system is Windows 7 and I have also installed Word, Excel, PowerPoint and Access 2003. Can I install Word, Excel, PowerPoint and Access 2007 as well?

    try this also
    Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint File Formats
    By installing the Compatibility Pack in addition to Microsoft Office 2000, Office XP, or Office 2003, you will be able to open, edit, and save files using the file formats in newer versions of Word, Excel, and PowerPoint .

    Yes, you can install different versions of Office side-by-side by doing a custom install of the second one as long as both of them are 32-bit versions. In your case, Office 2003 would be installed under C:Program FilesMicrosoft OfficeOffice11 (or C:Program Files (x86)Microsoft OfficeOffice11 if you are running the 64-bit version of Windows). When you install Office 2007, you need to Customize the install and select the older versions you wish to keep. If you have an older version of Outlook, it will still be uninstalled and only the latest version installed or retained. See this link for more details.

      If I run both side by side will there be any problems opening, editing etc., files in either versions?

      As I am running the 64-bit version of windows and use word 2003, how will this affect the install of word 2007, sorry slightly confused by your answer above as you state so long as both are 32-bit versions?

      There's no problem running them side by side (apart from Outlook, as Bruce points out).

      However, you can only associate the Office documents with one version of the other. In other words, when you double click on a .DOCX file, for example, it will open either with Word 2003 or with Word 2007 (by default, it will open with the one which was installed last). If you want to open the document with the other version, you must either a) start the application first and use File=>Open... to open the document or b) right-click on the file, and select open with=>(name of application). If the application is not listed click "Choose default program...", locate the program and select it.

      According to the MS website, a if the version of Office that created the file is installed, it will default to that version for opening the file under Vista or later versions of Windows. It doesn't specify for XP or earlier.

      The reference to 32-bit versions is about Office, not Windows. As long as both O2K3 and O2K7 are both 32-bit, this will work.
