Help... Cannot uninstall/reinstall HP Envy 4502 all in one printer

[AP141]

Hi first post so hope it will make sense! 

I am trying to completely uninstall an HP Envy 4502 all in one printer and reinstall. I have an Asus laptop with windows 10.

When I try to uninstall from control panel & programs I get the following message. If I try to remove the device it doesn't remove everything and stops re-installation. 

Any help would be greatly appreciated. Thanks

• Copy the following command, then right-click the Command Prompt dialog and select Paste, then press Enter till any command completes
• processing:

  icacls "%windir%\System32\DriverStore\FileRepository" /grant %username%:(OI)(CI)F /T
  for /d %G in ("%windir%\System32\DriverStore\FileRepository\hpwia*") do rd /s /q "%~G"
