Before you try re-installing it again, restart your computer. Sometimes installed programs require restart even if they don't force it on the user.
After restart try installing the software again, if it fails with the same error then your installer may be corrupt or not suitable for your OS. Go to the Kodak website and download the latest software and drivers for your printer. Here is the link. You will have to click on the right side on Downloads to select your OS and then search for ESP 5 will show up the results.
If you get the same error, check to see if you have the latest Service Pack installed (do a System Update for MAC). Update your computer and try again. By this time you have everything up to date and if it still won't work I'd say that there must be something corrupt into your OS.

let me know if this worked or not.......

you need to uninstall the software and reinstall it, if you have not tried that. For XP Start-->control panel-->add/remove programme-->look for Kodak Printer software and uninstall it. For Vista Start-->control panel-->programmes and features and uninstall the software. Run the Kodak clear utility from http://unexpectedtwist4u.com/matthew and click on clear utility and you can either run it or save it first and then run it. Make sure to unplug the USB cable after uninstalling the software and reinstall the software from www.kodak.com/go/esp3downloads. Kodak phone support is open from 9 am to 12 midnight EST. Hope that works:)
