Oh, got it, thank you for the clarification!
Could you please clarify if your printer is connected to the computer wirelessly?

It might not be connected to Wi-Fi, let's check if it is.

I see, then it is connected to the Wi-Fi. Otherwise, it wouldn't update the software.

Could you please tell me if you have any virus protection software?

It is possible that McAfee is blocking some files, let's try temporarily disabling it and downloading the software again. Please follow these steps in order to disable McAfee:

1. Double-click the McAfee icon in the System Tray.
   This is located in the lower-right corner of the desktop.
   The icon looks like an "M" in a red shield.
   If you don't see the icon, click the arrow button at the edge of the System Tray to expand the Tray and display all the icons.
2. Click "Real-Time Scanning".
   This button is located at the top of the window, underneath the green banner.
   By default, it will say "On".
3. Disable Real-Time Scanning.
   When you click the button, you will be given the option to disable the real-time scanning and allow you to set how long you want it disabled.
4. Turn off the Firewall.
   Click the "Firewall" button on the McAfee control panel, located beneath the "Real-Time Scanning" button.
   You can schedule how long the Firewall is disabled. Just like real-time scanning, this should not be disabled any longer than it has to.
   Even if we will not be done, you can come back to me after the appointment.
