Hello,
I have a Photosmart C6280 All in One printer which has been running perfectly even after upgrading to a pc running Windows 7 (and installing a suitable driver for that system). Now, however, I have a number of problems that have led me to conclude that I need to re-install the driver. All initial attempts failed and having looked at this blog I tried opening the util file and using the ccc route with option 4. Still nothing happened. I've now successfully (I think) uninstalled all but the Driver Software 13.0 Ref 2 which refuses to respond to anything I do. Can anyone help with this so that I can delete this file and re-install the software?
