If you had got your C11CA45201 unit without any Actius A800 driver CD or the latter is lost, you may choose to follow the links below. Without a special C11CA45201 driver to your unit, you won’t be able to use all its Sharp functionality. The basic Actius A800 driver from Windows is only able to support the minimum Vaio BX670P54 set thereof. You are really in need of a fully-featured authentic Actius A800 driver.
