Since I've heard of several peopple moaning about the Installtion of Office XP, here is my installation procedure. It worked each time so far on several Linux Distributions.
-> Install CX 3.0
-> Install IE6.0 via the CX Setup
-> Use the IE6.0 to install windows updates for win98
- There are 14 updates shown, install them
- Answer with "yes" the dialog after installing (if you check the microsoft update page again you'll see 6 packages left, ignore that)
-> Install Office XP
-> Use IE6.0, visit the microsoft homepage and install "Installer 2.0"
-> Use IE6.0, visit the microsoft office homepage and install SP3
Your Office XP is ready to go, have fun ! :)
