Office XP in different user account

[Mike]

I've got Windows XP Pro running on my PC with 2 user
accounts set up, both as administrator. I've also loaded
Office XP. Word/Excel work fine in one account.....but
when I switch to the other user account, and I try to
retrieve a file that was saved while logged-in under that
account, I receive a "cannot access file" message....

Can I not use one install of Office XP with two different
user accounts in Windows XP?

Thanks in advance for your help....
