Reinstall QuarkXpress 7.5 Evaluation

How to reset QuarkXpress 7 for Windows Evaluation, so you can reinstall and extend the Trial period.
We started with QuarkXpress 7.0, updated to 7.01. At some point the software wouldn't start, so we uninstalled it.
We then tried to reinstall.
The installer refused to reinstall. Obviously the uninstaller left something behind, that prevented the reinstallation of Quark Express 7 eval.
After removing the following folders, we manage to reinstall Quark Xpress 7 and try some more.
C:\Documents and Settings\All Users\Application Data\Quark
C:\Documents and Settings\me\Application Data\Quark
