Severity

Warning

Message

This Windows Installer database contains a driver ([FILE_NAME]) which is not correctly signed (Table: File, Key: [FILE_KEY]).

Background

A signed device driver includes a digital signature (an electronic security mark that can indicate the manufacturer of the software, as well as validate the original contents of the driver package). If a driver has been signed by a manufacturer that has verified its identity with a certification authority, it is confirmed that the driver actually comes from that publisher and has not been altered. If a user tries to install an unsigned driver, Windows displays a warning and prompts the user.

Resolution

The following resolutions are available.

Manual Fix

A signed version of the driver should be delivered by its manufacturer. Alternatively, Windows Driver Kit (WDK) from Microsoft can be used to sign the driver with a trusted certificate.

Basic Auto Fix

No resolution is available.

Advanced Auto Fix

Unsigned drivers are removed in a Windows Installer transform.

This fix is enabled by default.

Caution:This might have a high negative impact on application functionality.
