Thank you for the information!
Since these steps have not work so far, plase try the steps in this HP document: The Progress Bar on the Software Installation Stops or Stalls
If these steps cannot resolve the issue, I would try installing it on another computer. This would determine whether or not the printer is at fault, or the computer. If it installs on another computer successfully, then we know there is a complicated software conflict on the one computer. I would reinstall the operating system of that computer, and the issue will be resolved.
