hello there. i'm trying to install the drivers of my all-in-one printer, hp photosmart c3180 and all i get is this error: first, the installer asks me for admin permisions, and then this windows appears. i tried the drivers from the cd and from hp's website. i've also repaired permisions but nothing changes. i have installed these drivers before in my machine (17" intel iMac CD) so it's not impossible. please, help me, i need to print something for this week. thanks.
