    hwndParent - supplies the window handle used for the PRERELEASE message
        box that indicates an OLE registration has hung.

    InfHandle - supplies handle to inf containing the specified SectionName.

    hProgress - handle to progress gauge that gets ticked every time we
        process a file.

    StartAtPercent - Position where the progress window should start (0% to 100%).

    StopAtPercent - Maximum position where the progress window can be moved to (0% to 100%).

    SectionName - Supplies the name of the section contained in the INF
        specified by InfHandle that lists OLE control DLLs to be
        registered/installed.

Return Value:

    Boolean value indicating outcome. If a file to be registered is
    not present, that is NOT reason for returning false.
