install office 2003 and 2007 on one computer for different users

[太白居士]

There are 5 users account on my computer, and installed office 2003 for all
users.

Now I want to install office home and student 2007, just for user A, B, C.
And user D, E keep using office 2003.

Can I do that? If can, how to do?

Thank you.
