Is it possible to use Office 2003 and 2007 on same computer?

[linksgolfer]

Office 2007 is a significant change from previous versions I would like to
get familiar with 2007 gradually while continuing to use 2003 for my work.
Can I have both versions installed at the same time?

You have to choose between Outlook 2003 and Outlook 2007 because you can
only have one or the other, but you can have both 2003 and 2007 versions
of the other Office applications. If you want to keep the 2003 versions
of Word, Excel, etc., alongside the 2007 versions, then choose a Custom
installation of 2007, and choose to keep the 2003 versions in the
Installation Options tab.

As a precaution, back up Word 2003's normal.dot template and any custom
templates you created, autocorrect list, and custom dictionary, and
Outlook's .pst file(s), before you install the 2007 version. See

Thanks for the advice that worked out perfectly

I would recommend a different method to do this.
If you install just a part of 2007, you will no longer beable to install
some updates from office 2003, thus causing a big security hole.

A better (and safer) way to do this is with a virtual machine, yes it takes
a bit more maintanence as you have to install some virtual workstation
software (either VMWare workstation edition or VirtualPC or whatever) and
then install the office on top of that other operating system.

This is only if you care about MS updates, which you should.
