If it makes you feel any better,

I'm having the exact same problem :(

and its a new computer with a 750 GB hard drive, a quad processor, extremely high graphic/sound card, basically it's like, an amazing computer,

so i definately meet the requirements,

but i have no idea why it isn't working, !

its really frustrating,

im the administrator, i tried everything i could,

but whenever i try to access my DVD drive that i put it in it says "Drive 'D:' is not accessable, ACCESS DENIED!"

so yeah, :(
