ActiveX Installer on Vista Home Premium

Hi all,

I need to install RPM (Rational Portfolio Manager IBM) on my laptop,

My laptop is running Vista Home Premium,

One step of the RPM installation under vista Entreprise is: Turn On the

'Activatex Installer', But unfortunatelly this is not available in my

windows

function list.

Do you know how can I turn on 'Activatex Installer' on Vista Home Premium.

Thank

Akeem
