Retrieves the version of the system driver.
def get_driver_version(product_guid: str) -> int: ...
This method retrieves the version of the system driver. 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 22.214.171.124 would cause the value 0x000200200006001C to be returned.
If the driver 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:
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.
