Problem uninstalling openoffice 3.

[Konstantinos Chouchoulis]

Dear Mr or Ms,
 I have installed openoffice 4.1 but I can not uninstall the openoffice 3.
 I have tried from the control panel (windowsxp) it starts the procedure
but in the end the openoffice 3 is still there.
 I have tried the free Eusing registry cleaner but it didnot fix it either.
 I look forward to your reply.
With regards,
Kostas
