This code means VxD Loader (Vxdldr) returned an unknown result. For example, there could a version mismatch between the device driver and the operating system.
To resolve this issue, follow the recommended solution. If that does not work, try removing the device from Device Manager and then running the Add New Hardware Wizard in Control Panel.
Have a look at Device Manager to see if there are any devices with errors.
Also have a look at the Event Log (System) to see if there are any errors.
