get_module_version Method

Retrieves the version of a given product module.


def get_module_version(product_guid: str, module: int) -> int: ...


This method retrieves the version of the product module specified by Module. The value is returned as a 64-bit integer composed of four 16-bit words that each correspond to a piece of the overall module version. For example, a version of would cause the value 0x000200200006001C to be returned.

If the specified module is not installed, this method returns 0.

ProductGUID is used to distinguish between driver installations performed by different applications. Such information is necessary to guard against unexpected situations such as, e.g., the driver being uninstalled by one application despite other applications still needing it.

Therefore, to ensure proper operation, it is critical that each individual application have its own unique ProductGUID value, and that applications (and their installation scripts) use that value when calling any of the following methods:

The Module parameter specifies which driver module to query the status of. Possible values are:

MODULE_PNP_BUS0x00000001PnP Bus Driver (.sys file).

This module must be installed if the application wishes to make use of Plug-and-Play (PnP) storage features. PnP storage devices are those visible as disks in the Device Manager, and the system treats such storage devices differently from other purely virtual devices.

The filesystem driver must be re-installed anytime this module is added or removed.

MODULE_DRIVER0x00000002Core Product Driver (.sys file).

The product's filesystem driver module provides the core of its functionality; it must be installed for the product to function correctly.

MODULE_HELPER_DLL0x00010000Shell Helper DLL (CBFSShellHelper20.dll)

This module provides supplementary functionality; please refer to the Helper DLL topic for more information.

Note: Not applicable when calling the get_driver_status method.

This method is available in both the class API and the Installer DLL included with the product; please refer to the Driver Installation topic for more information about the latter.

Note: This method cannot be called within events.
