Uninstalls the component's system driver.
function Uninstall(CabFileName: String; ProductGUID: String; InstalledPath: String; Flags: Integer): Boolean;
This method is used to uninstall the component's system driver. If the system must be rebooted to complete the uninstallation process, this method returns True; otherwise, it returns False.
Important: To upgrade the component's driver, just use the Install method, do not uninstall it first!
Please refer to the Driver Installation topic for more information.
The same values must be passed for the CabFileName, ProductGUID, and InstalledPath parameters as were passed when Install was called; please refer to its documentation for more information.
Flags specifies which versions of the component's system driver should be uninstalled, and should be set by OR'ing together one or more of the following values:
|UNINSTALL_VERSION_PREVIOUS||0x00000001||Uninstall modules from previous product versions.|
|UNINSTALL_VERSION_CURRENT||0x00000002||Uninstall modules from the current product version.|
|UNINSTALL_VERSION_ALL||0x00000003||Uninstall modules from all product versions.|
This method is available in both the component API and the Installer DLL included with the product; please refer to the Driver Installation topic for more information about the latter.
