I got both a iMac and a MacBook Air, both on Snow Leopard (with Rosetta). I want to Nikon Scan 4 (as I don't like Vuescan or Silverfast. I install Nikon Scan 4 on to MacBook Air, which works perfectly fine, but when I install it on my iMac, it doesn't work (it says: "no scanner detected".) The hardware of iMac is fine, because it can work with another HP scanner. Just the software doesn't work. Could anyone help? Thank you in advance.
Macbook, 2010 iMac 27, Mac OS X (10.6.8), ipod touch, iphone 4
