Implementing Finish-Install Actions

Installers (a class installer, class co-installer, or device co-installer) supply finish-install actions. A finish-install action can run an executable program, create a process, create a thread, or execute code in the device driver installation finish-install process.

To implement finish-install actions, an installer:

  1. Sets the DI_FLAGSEX_FINISHINSTALL_ACTION flag when the installer processes a DIF_NEWDEVICEWIZARD_FINISHINSTALL DIF code and returns one of the following error codes:
    • ERROR_DI_DO_DEFAULT if it is a class installer without finish-install wizard pages.
    • NO_ERROR if it is a class installer with finish-install wizard pages or a co-installer with or without finish-install wizard pages.
  2. Performs the finish-install actions when it processes a DIF_FINISHINSTALL_ACTION request.

    An installer returns one of the error codes in the following table.

    Error codeMeaning

    ERROR_DI_DO_DEFAULT

    Class installer: The class installer has successfully run its finish-install actions and is requesting Windows to perform its default processing. A class installer should also return this error code if it has no finish-install actions.

    Device or class co-installer: Co-installers do not return this error code.

    NO_ERROR

    Class installer: The class installer has successfully run its finish-install action. Windows should not perform its default processing.

    Device or class co-installer: The co-installer has either successfully run its finish-install actions or has no finish-install actions.

    Microsoft Win32 error

    The installer encountered an error, but the finish-install action should be attempted again. Returning a Win32 error code indicates that Windows should run another finish-install process to complete the finish-install actions the next time the device is enumerated.

     

    Note   If a finish-install action fails and should not be attempted again, a class installer returns ERROR_DI_DO_DEFAULT and a device or class co-installer returns NO_ERROR.
