DPInst supports the following command-line switches that set the DPInst configuration flags that are described in Setting DPInst Configuration Flags and additional switches that further modify DPInst operation:

/a

Sets the installAllOrNone flag to ON, which configures DPInst to install drivers in a driver package only if all of the drivers in the installation package can be installed.

/c

Configures DPInst, if DPInst is called at a command prompt, to display the text of log messages in the Command Prompt window.

/d

Sets the deleteBinaries flag to ON, which configures DPInst to delete the binary files that were copied to a system when a driver package was installed.

/el

Sets the enableNotListedLanguages flag to ON, which configures DPInst to enable all of the supported languages that are not explicitly enabled by language XML elements in a DPInst descriptor file.

/f

Sets the forceIfDriverIsNotBetter flag to ON, which configures DPInst to install a driver on a device even if the driver that is currently installed on the device is a better match than the new driver.

/h, /?, or /help

Configures DPInst to display help information about DPInst command-line options. If DPInst was called at a command prompt, DPInst displays the help text in the Command Prompt window; otherwise, DPInst displays the help text in a message box.

/L language-ID

Configures DPInst to display the text, bitmaps, and icon for the language that is specified by a language-ID value. The language-ID value can be specified in either hexadecimal or decimal format. For a list of the languages and corresponding language identifiers, see DPInst Multi-Language Support. If DPInst supports the specified language and runs on a Windows operating system in which the language is installed, DPInst will use the specified language. For more information about using the /L switch, see Testing Language Customization.

/q or /s

Sets the quietInstall flag to ON, which suppresses the display of wizard pages, user dialog boxes, and other user messages that DPInst and Windows generate. The quietInstall flag works with the presence of a end-user license agreement (EULA) page and the suppressEulaPage flag.

/p

Sets the promptIfDriverIsNotBetter flag to ON, which configures DPInst to display a user dialog box if a new driver is not a better match to a device than a driver that is currently installed on the device. The user dialog box informs a user of this situation and provides an option to replace the driver that is currently installed on the device with the new driver.

/path DPInst-working-directory

Sets the DPInst working directory to DPInst-working-directory. DPInst searches for driver packages in the DPInst working directory and in subdirectories under the working directory that are specified by subDirectory XML elements in a DPInst descriptor file. For more information about setting the DPInst working directory and specifying subdirectories under the working directory, see Specifying the Location of a Driver Package.

/se

Sets the suppressEulaPage flag to ON, which configures DPinst to suppress the display of a EULA page. The suppressEulaPage flag works with the quietInstall flag and the suppressWizard flag.

/sa

Sets the suppressAddRemovePrograms flag to ON, which configures DPInst to suppress the addition of Add or Remove Programs entries that represent the driver packages and driver package groups that it installs.

/sh

Sets the scanHardware flag to ON, which configures DPInst to install a driver package for a Plug and Play (PnP) function driver only if the driver package matches a device that is currently configured in a computer and if the driver package is a better match for the device than the driver package that is currently installed on the device.

/sw

Sets the suppressWizard flag to ON, which suppresses the display of wizard pages and other user messages that DPInst generates. The suppressWizard flag works with the presence of a EULA page and the suppressEulaPage flag.

/u inf-file-path

Configures DPInst to uninstall a driver package whose INF file matches the INF file that is specified by inf-file-path. The path that is specified by inf-file-path is relative to the directory that contains DPInst.exe.

Examples

The following command includes the /q and /se command-line switches, which configure DPInst to operate in quiet-install mode, whether or not a eula XML element is included in a DPInst descriptor file. This command suppresses all of the wizard pages, user dialog boxes, and other user messages that DPInst and Windows generate.

dpinst.exe /q /se

The following command includes the /q command-line switch, which configure DPInst to operate in quiet-install mode. However, DPInst will operate in quiet-install mode only if a eula XML element is not included in a DPInst descriptor file. If a eula element is included, DPInst does not operate in quiet-install mode.

dpinst.exe /q

The following command includes a /se command-line switch, which suppresses the display of only the EULA page.

dpinst.exe /se

The following command includes the /q and /se command-line switches, which configure DPInst to operate in quiet-install mode, including suppressing the EULA page. The command also includes the /f command-line switch, which forces the installation of a new driver package for a device that is configured in a computer, even if the driver package that is currently installed on the device is a better match for the device than the new driver package.

dpinst.exe /q /se /f

The following command includes the /sh command-line switch, which configures DPInst to install a driver package on a device that is configured in a computer only if the new driver package is a better match for the device than the driver package that is currently installed on the device. This command facilitates using an installation package to batch install driver packages for devices that are configured in a computer. Although the installation package might contain a large number of driver packages, DPInst will install only driver packages that are better matches for the devices than the driver packages that are currently installed on the devices.

dpinst.exe /sh

The following command includes the /u command-line switch, followed by the Abc.inf INF file, and the /d command-line switch. The /u command-line switch uninstalls the driver package that is associated with the Abc.inf INF file from all of the devices on which the package is installed. The /d command-line switch deletes the binaries that were copied to the system when the package was installed and deletes the package from the driver store. If the driver package is signed, the corresponding catalog file must be present in the same directory in which Abc.inf is located.

dpinst.exe /u abc.inf /d
