Why do I get the error 'Failure to load the device plug-in' when connecting to a CAN device?

In MATLAB R2017b, I am trying to construct a CAN channel connected to my Vector VN1610 device, either using the command

canChannel('Vector','VN1610',1)

or through Vehicle CAN Bus Monitor. However, I receive the following error message:

Error using asyncioimpl.Channel
Failure to load the device plug-in.
Error in asyncio.Channel (line 104)
            obj.ChannelImpl = asyncioimpl.Channel(devicePluginPath,...
Error in can.vector.Channel (line 213)
        obj.AsyncioChannel = asyncio.Channel(devicePath, converterPath, asyncioOptions, [Inf, 0]);
Error in canChannel (line 71)
        channel = can.vector.Channel(varargin{:});

The reason for this error message might be an outdated vendor device driver.

Download the Vector drivers as described in the following article:

In the Vector driver setup, make sure you select to upgrade the drivers for your particular device family.
