permission

Hello

I am running Windows Vista RC1 Evaluation copy. Build 5600
I am trying to install the Sony Ericsson PC Suite Software and I get so far
and the installation stop and I get a dialog box telling me i do not have
sufficient privileges and I should log in as an administrator. I have doe
this and I still cannot install the software, I have noticed that for the
program files folder and the windows folder I do not have full control on
file permission on those folders. When I try to give myself or the
administrator full control I get access is denied. Does anyone know if there
is a way I can get round this?

Regards

Richard
