This application "HP Scan" cannot be opened

Question

I just updated to Yosemite on my MAC. Since then, I haven't been able to use my printer. I've tried to uninstall and reinstall it. Now when I click on it, I get the message, "this application "HP Scan" cannot be opened". So I've tried to click on "uninstall" from the applications menu, I get the same message. I've tried to scan directly from the printer, it won't allow me to, says I need to do it from my computer. I have a HP Photosmart D110A, used it without problems prior to updating to Yosemite. I've also tried unplugging and plugging in the cord from the printer to the computer, as it can be wireless. Doesn't make a difference. What can I do to resolve this?
Thanks,
Kelly

Hi Kelly,
The HP Scan application is not avaialble for your printer for Yosemite and not intended for the operating system.
First open the Applications folder and then the Hewlett-Packard folder, select Uninstall and completely remove the HP software.
Additionally, manually remove any reminder of the incompatible software, so that will not prevent getting the correct software:
From the computer desktop, double-click the Macintosh HD icon.
Double-click the Library folder.
Double-click the Printers folder.
Right-click the HP folder, and then select Move to Trash.
When prompted, type the Administrator name and Password for the computer, and then click OK. Wait for authentication to complete.
Double-click the PPDs folder.
Double-click the Contents folder.
Double-click the Resources folder.
Locate your printer in the printer list by searching for D110, and then right-click on your printer and select Move to Trash.
When prompted, type the Administrator name and Password for the computer, and then click OK. Wait for authentication to complete.
Click the Trash icon on the taskbar, click the Empty button, and then click OK to empty the trash.
On the upper-left corner of the computer desktop, click the Apple menu icon (), and then click System Preferences on the drop-down menu.
Double-click Printers & Scanners.
In the Printers list, click your HP printer, and then click the Minus button () to delete it.
Note: a such may no longer be listed. simply skip this step if the printer was already removed.
 Next, follow these steps to install the printer on Yosemite, the drivers are availble via Apple Software Update:
