Vista Tutorial - MSN Games - applet installation

Hi

the games in MSN used to work perfectly, however all of a sudden they have
stopped working and the software keeps requesting that I install an Active X
applet. The only problem is that it's not offering me the option to install
this. I have changed the security settings in Internet Explorer to low to
allow the installation of such applets, I have restarted my computer several
times and searched various forums, but to no avail!

Please help.

Thanks.
