C4780 scanner not working

[Rooby2Shoes]

I seem to have a problem scanning which I didn't have before. I don't understand the error message.

I tried just installing new software from the HP website as I don't have the original disc anymore. I seem to now have a wireless connection which is a bonus (gave up on that before but obviously new software mended that fix) however I still can't scan and I have an urgent document to send tonight.

I double checked I had downloaded Full Software (it confirmed I had)

This is the error message I get.

Please advise what I can do in very simple terms. I am not an I.T expert and find a lot of these things hard to understand or follow.

c:\Program Files (x86)\HP\Digital Imaging\bin\hpqtsshctui.dll is either not designed to run on windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator

- it worked on windows before (just stopped working)

- where would it get an error from?!

- I have reinstalled software it doesn't fix the problem

- I am trying to scan from the HP solutions 'Home' screen

Please can someone help?!

Seems a lot of people suddenly have a scanner issue, what is causing this for everyone?

Hi, 

Step 1: Uninstall your printer from Programs and Features

1. If your printer connects to the computer with a USB cable, disconnect the cable from the printer.
2. Search Windows for programs and features, and then click Programs and Features in the list of results.
3. In the list of installed programs, click your HP printer name, and then click Uninstall or Yes.
4. If a User Account Control message displays, click Yes.
5. Follow the on-screen instructions to complete the software removal.
   If the software uninstall process does not start or an error displays while uninstalling, download Fix problems that block programs from being installed or removed (in English) from the Microsoft website, and then try uninstalling again.
6. After the software uninstall is complete, restart the computer.

Step 2: Remove the printer from the devices list\

To complete the uninstall, remove the printer and any Windows print drivers from the Windows Devices and Printers list.

1. Make sure the printer is turned on and in a ready state.
2. If your printer connects to the computer with a USB cable, disconnect the cable from the printer.
3. Search Windows for devices, then click Devices and Printers in the list of results.
4. Right-click the icon for your printer , click Remove Device, then follow the on-screen instructions to complete the printer removal.
   If multiple icons exist for your printer, remove them all. 

Step 3: Remove from Print server Properties:-

Watch this youtube video from 58 second it shows how to remove printer from print server properties. 

Step 4: Remove files from temp and prefetch

Select All files and delete ( some files may do not delete , you can skip )

Step 3 - which YouTube video?

Step 4 - what do you mean by go to RUN, where is RUN?

And how do you know all files in this folder need to be deleted? What if it deletes something not relating to the issue?

Hi

Sorry forgot to paste the link ..  My bad

Files your deleting from TEMP folder 

These files are typically located in the standard temporary directory, /tmp on Unix machines or %TEMP% (which is log-in specific) on Windows machines. Atemporary file created with tmpfile is deleted automatically when the program exits or the file is closed.

Files your deleting from PREFETCH 

The next time you turn on your computer, Windows refers to these files to help speed the start process. The prefetch folder is a subfolder of the Windows system folder. 

You can skip this if not willing to perform the steps.
