normally windows applications can not run/be installed on Linux, but you can try to use wine (which is a Windows emulator on linux)
i am not sure if it will be able to install the office, i have tried it with simple exe files and it ran them
You can't install M$ Office 2000 and latter under wine in linux, you can use Office 97, but if you have a powerfull machine you can use xen (the latest and gratest wirtualisation software for linux and other unix's) and install Window$XP as a guest operating system under linux.
The M$ and Novell deal included improved native support for mono (dot net for nix) wich is financed by novell, as well as improved support for M$ Office under Suse's build of oppen office, and I suspect we'll soon see a M$ office for linux.
My theory is that the M$ and Novell deal is mainly directed against Sun Microsystems and sun's java as well as RedHat the two arch enemy's of the two older enemy's M$ and Novell.
My enemy's enemy is my friend?
