This is because of a malfunction that occurred while the software was installing. Somehow it managed to open the process even though it wasn't fully installed. You can open up your Task Manager by pressing CTRL + ALT + DEL and click on the 'Processes' tab, you should see a process named PrinterProDesktop.exe, proceed by clicking on it or select it and then kill the process by clicking the 'End process' button located at the bottom on the right of your Task Manager window.
