office xp uninstall override

[Aen]

I just inherited a windows 2003 server that has Word 2002 and Excel 2002 installed on it. When i try to remove it from the server it is asking for the source disks. looking for the excel.msi and word.msi files. I have a copy of office xp but it can not locate those files and i can not get rid of those prgms. Server they gave my group has a 4 gig C drive and its killing me on space. Need to get it usable for a month till our new server comes in for replacement.

Anyone know how i can fix this?
