Did you manually remove the folder for the software? If not, do that and then run the registry module in Ccleaner Slim to remove any orphan files. Get Ccleaner Slim from the link below.
Keep in mind, you must run the removal tool each time you have a failed attempt at installing.
You could also try a custom installation using your original disk. You should be able to de-select one or more of the modules. For instance, if you don't use the FAX function, don't install it. If the scan function is bad, de-selecting it may allow installing the printer function.
Have you tried installing when logged in as the Administrator.
Do you have any other scanner software installed?
