side by side configuration is incorrect

[JennyW2]

I can't seem to install the software for my new computer. I keep getting an error box that says "The application has failed to start because its side-by-side configuration is incorrect." Any idea how to solve this problem?

I understand that you are unable to install the software for your HP ENVY 4520 All-in-One Printer.

Let's go through a few steps to uninstall and reinstall the drivers:

Please follow the steps provided to uninstall the printer software in the link: Uninstalling the Printer Software (Windows)

Also, please follow the steps provided below to completely remove the printer software from printer properties.

Steps to remove printer driver files from Print Server Properties:

1. Open the Print Server Properties dialog window by doing one of the following:
   • Click the Start menu and in the search field type 'printui /s /t2' (without the quotes), and then press Enter or click it in the search list.
   • Press WINDOWS-R on the keyboard to bring up the Run window, type in 'printui /s /t2' (without the quotes), and then press Enter or click OK.
   • From the Start menu or the Start screen:
   • Open Devices and Printers.
   • Select any printer and then click "Print server properties" at the top of the window.
