If I had to guess I would say that the driver is not able to handle my particular configuration where I have set through Windows that my virtual memory cache be on a non system drive. Every other software that I have installed have had no problem with that. In an attempt at soving the issue, I unstalled the HP software from C:\ to reinstall it on D:\ but the software doesn't let the user choose the installationb path (really, HP??!).
