2 Operation 2.1 Driver Installation 2.1.1 Operation Sequence 2 Operation At first the setup application checks whether there is an existing installation on the target system. If that is the case and if it differs from the current setup it is uninstalled no matter whether the existing installation is older or newer. Afterwards, the setup performs a cleanup based on the information available in the driver package to install. During this cleanup all drivers that match one of the hardware IDs supported by the driver package are uninstalled, including their assignment to corresponding devices. The cleanup is important in cases the removal of an existing installation failed for any reason or drivers have been installed in another way, e.g. by means of system tools like the device manager. In the next step the setup application performs a preinstallation of the driver software. This means that the driver will be installed on the system but not yet assigned to any device. The system assigns the driver as soon as it recognizes that the corresponding device is connected. Before the driver is assigned the system checks whether there is another matching driver that is a better choice for the device. The decision which driver is better depends on the operating system, the driver version and signature of the driver package. Both the removal of an existing installation and the additional cleanup make sure that only the driver provided with the setup is present on the system and successfully assigned to the corresponding device, independent of the operating system and no matter whether the driver package is installed the first time, or an update or a rollback is performed. If the setup is running with a graphical user interface it prompts the user at the end of the installation to disconnect and reconnect the device. This ensures that the driver is also assigned in the case the user not yet connected the device to the system or in the case the system cannot recognize the current connection for any reason. The user may ignore this request and can connect the device at a later point in time to complete the installation successfully. In the case the setup is executed and detects an existing installation that is identical the user is just informed that the installation completed. No further installation steps will be performed. 2.1.2 System Setup Dialogs Depending on the operating system and the driver package (signed/unsigned, setup class) Windows may rise additional setup dialogs, e.g. to prompt the user to confirm installation of an unsigned driver, to trust the driver vendor or to assign the installed driver to a connected device (Found New Hardware Wizard). The PnP Driver Installer minimizes their appearance and integrates the remaining, inevitable dialogs as good as possible into its user guidance. Under Windows XP and the corresponding server systems the Found New Hardware Wizard may appear at the end of the installation or later when the system detects a connected device. This system wizard prompts the user to assist the assignment of the preinstalled driver to the device. The user just has to follow the instructions of the hardware wizard, i.e., he can choose the option "No, not this time" on the first page and should continue with "Next" on every following page until the wizard finished. Windows setup dialogs can be avoided by signing the driver package (see section 2.5). PnP Driver Installer Reference Manual 7
