I tried to re-install my HP Photosmart C4100 Series disk but it stopped with a message saying that Certclas.inf, USCStor & USB Print were missing.
Your installation package may suffer from file corruption. Download a new setup from HP Support website and it'll surely fix your problem. Also, perform a clean installation of the software for better results.
First your hp drivers uninstall and then download hpc4180 universal driver download. And try install for good result. good luck
