Office 2002/XP does not install due to bug 5163. This bug is unlikely to ever be fixed.
The single platinum test report above is from a user who had a slipstreamed, volume licensed installer that did not ask for a registration key, and hence was not affected by bug 5163. Unless you have such a copy, you will not be able to install Office XP in Wine.
For the determined, there is a hack/patch attached to bug 5163. It will not apply to current Wine; you will have to get the source for 1.0.1, patch it, and pray that it compiles on a modern system (it might not). This hack is unsupported; use at your own risk.
Guidelines for Submitting Test Reports
Specify exactly which edition of Office 2002/XP you tested (Standard,
Pro, etc.) This is crucial--bugs that affect one edition may not affect
Specify exactly what type of install you tested (Typical, Custom, Minimal, etc.)
your report to the installer only. Reports on the performance of
individual apps should be filed under their respective AppDB entries.
Problems with running any of the apps should only be mentioned if it is
clear that it is due to a problem with the installer.
If you used any overrides during the install,
please list them and explain exactly what problem each override was
needed to solve.
