My two HP All-in-One machines, different models purchased at different times, now display the same message: "No Scan Options_You need to install or run HP software for this feature." Purchasing upgrade software from the HP site did nothing to restore operation. What I'm hot about is the company sold these machines as all-in-ones, but the scanners cease operation, without warning, in about one year. I want an explanation and my money back for the ineffectual upgrade which arrived today.
