Word won't open after deleting Office 2003 Installation filtes

[Craig Lindstrom]

I'm getting a message
"the feature you are trying to us is on a network resource that is
unavailable.

Click ok to try again, or enter an alternate path to a folder containing the
installation package "MSO.MSP" in the box below."

then word doesn't open.

I tried inserting an original install disk for office 2003, but there are no
MSO.MSP files on the CD.

Thanks!
