LX02 Intel HD 3000 graphics driver -- does not install; "unsupported system".

Hi everyone,

I know this topic has been posted before, but I am quite desperate here...

I have followed the steps in this post http://en.community.dell.com/support-forums/laptop/f/3518/t/19426589.aspx?PageIndex=1

but nothing,

In the Device Manager under the Display Adapters I can only see the Nvidia Gt 555M, there is no Intel HD 3000 or other...

Can someone please help me here??

Thanks a lot!!
