I have an EasyShare Z710. I was able to get it to work in 2 steps...
#1 - when I plugged it in, it would detect as a Kodak Z710, but, the
driver wouldn't install successfully. I had to go into device manager and change the
driver to MTP USB Device. Once I did that, the system recognized it normally as a Kodak Z710 each and every time I hooked it up and turned it on.
#2 - the Kodak software didn't seem to like Windows 7 without compatibility mode, but, oddly enough, when I put it into compatibility mode, it came up with a message asking me if I wanted to turn it off? Anyhow, I set it to Vista compatibility and the issues are gone!
Best of luck!
