Office jet Pro 6978 Driver will not install on windows 7

[JFHamelin]

I get the "intall Failed, the software required for your device could not be installed" message when trying to install the Office Pro 6978 driver on a windows 7 Enterprise (service pack 1) 64 bit Lenovo.  Tried "run as" administrator.  I can get through the first few steps of the install process, I can see the printer, then it fails.  The "details" button doesn't lead to anything.  For now, I'm stuck using ePrint.   Any suggestions ?

Hi, @JFHamelin - Greetings!

Thanks for reaching out! I'd like to be of your assistance 🙂

I see that you are having issues while installing the Officejet printer on your Windows 7 PC. I'd suggest a clean install to try and fix the issue. Here are the steps:

• First, unplug the USB cable from the printer if present.
• Go to Control panel – Programs and feature – Select all the HP Officejet printer entries and uninstall them.
• Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
• Restart your computer.
• Click the bottom-left Start button on desktop, type device manager in the search box and tap Device Manager on the menu.
• Once in device manager, click on the view tab in the top & choose “Show hidden devices”.
• Then from the device manager list, check the entries under “Printer”  – If there are any entries, please right click and choose “uninstall” – In the confirm device un-install pop-up, make sure you select the box which says “Delete the driver software for this device".
• Also, check the entries under "printer queue" and "imaging devices" and repeat the same exercise. Delete any printer entry or any entry which says “Unknown device”.
• Once done, close device-manger. Then press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" (there is a space between .exe & /) and press enter.
• Under print server properties, go to drivers - remove any entry there as well.
• Again, go to run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.
• Open run again, type “%temp%” and press enter to get the temporary files. Delete all the files here. Skip the items which cannot be deleted.
• Now restart your computer again.
• Open the Run window again, type “services.msc” and press ok to get services window.
• Scroll down to “Remote Procedure Call (RPC)” – right-click and go to properties. Make sure the service is started and startup type is “Automatic”.
• Now scroll up and go to “Function Discovery Provider Host” – right-click and select properties – Change the startup type to “manual” and start the service.
• Repeat the same exercise on “Function Discovery Resource Publication” as well.
• Click on http://ftp.hp.com/pub/softlib/software13/printers/OJ6970/OJ6970__Basicx64_1975.exe and install the software.
• Connect the USB cable if prompted and follow the on-screen instructions to complete the installation.

Please let me know if this resolves the issue, or if you require further assistance!
