Hi
I am having a similar problem. I have recently upgraded to a new computer running Windows 8.1. I have downloaded the full software package for my Deskjet 2050 (J510a) and installed it. The basic printer function work fine but i have no "toobox" to check ink levels, print a test page etc. The DJ2050 icon appears on the desktop and start menu but clicking on it does no do anything. The command to shortcut will not invoke directly from the relevant directoty either.
Any assistance to find how to get this software would be appreciated.
