a registry problem will not let me install office 2003 or office 2

[Guest]

please can someone help? i am running xp sp2.
When i try to install office 2003 or office 2000
i get the following error message
HKEY_LOCAL_MACHINE\Software\Classes\.pps\PersistentHandler.
This stops the installation & reverves the process back to nothing.
i have been using eusing regisrty cleaner for 4 months & have avg anti-virus
installed. Also recently started using cyber defender internet security to
remove spyware.both eusing & cyber defender have files in quaratine but
nothing relating to the above mentioned error.

First uninstall the trial version before trying to install the licensed
version. You can not upgrade the trial version.
