What is the difference between the installation options:
Install gives you full control over the installation process. You can select the path and add Service Center to the Start menu.This option is a good choice for your personal system while you are becoming familiar with PC-Doctor or if you want to keep PC-Doctor installed for extended testing.
Quick Install and Run is for normal testing in the field or repair center. You can begin testing in a few moments, and PC-Doctor will automatically uninstall the next time the computer boots.
