Office 2003 and Office 2007 co-existence RRS feed

  • Question

  • Hi Forum,


    I am supporting a development team that is in the process of upgrading a number of Office applications from 2003 to 2007.  In order for them to be productive in this endeavor, they require both Office 2003 and Office 2007 to be installed on their workstations.  The issue is that in order for this to work, they are required to run the installation for each version in order to get access to the desired version.


    Is it possible to install both Office 2003 and Office 2007 so that they can co-exist without the need to explicitly re-install?

    From the end-user POV, it can be done, but it's not recommended or supported by Microsoft.

    From the Developer POV, it's definitely not recommended and, in some cases, won't work. A lot depends on your programming environment and what kind of applications these are.

    Best would probably be for you to invest in some Virtual Machine software (such as VMWare or Virtual PC) so that the developers can quickly switch between the two environments, but they won't interfere with each other.

    Even if you decide to go with a parallel installation, there's really no good way to avoid each needing to configure itself when it's started after the other has run. There were a number of paradigm shifts going from office 2003 to Office 2007 and each will want (and need) to re-register itself and its own components.
