I just want to use both office 2007 and office 2003 while I am getting use
to
office 2007. Is it possible to run both on one computer?


Yes, with one issue with Outlook, with a custom install allowing 2007 to not
overwrite the 2003 version programs. Outlook can only be installed by one
suite (I actually like 2007's better than 2003's version in most respects.)

There is also an issue with Word re-registering itself and that issue is
easily fixed by a registry edit. See:
http://support.microsoft.com/kb/928091/en-us about 1/2 way down page for
Word fix. You need to do two registry edits, one for Office 2007 which is
identified in the registry as Office 12 and an identical one in Office 11
which is Office 2003's registry ID.

Now, Microsoft does not recommend the registry edit "You can bypass the
auto-registration. This enables Word 2007 to start faster. However, we do
not recommend this because Word may not function correctly if it cannot
auto-register itself" but I have not had any issues with that edit in the
years I have used the fix on Office 2000, 2002, 2003, 2007 and now 2010
beta. YMMV of course.
