First, make sure to uninstall the software completely from the Control Panel/Add-Remove Programs section. Once that's done, then delete the printer from the "Printers" folder. Now, instead of installing the printer software from the CD, create a folder on your desktop and copy ALL files from the CD to the folder on your desktop. Once that's done, restart the computer in "Safe Mode", then open the new folder and double click on the "Setup.exe" file found inside. The software should install correctly.

Hope this helps.
