Why I get a error when I build Simulink example for EV3

I checked MATLAB is well connected with EV3,use h = legoev3('wifi','192.168.0.101','001653450ca3')

h =

legoev3 with properties:

      FirmwareVersion: 'V1.09E'
           HardwareID: '001653450ca3'
            IPAddress: '192.168.0.101'
    CommunicationType: 'WiFi'
         BatteryLevel: 100
     ConnectedSensors: {''  ''  ''  ''}

Set Hardware board: LEGO MINDSTORMS EV3 Set IP address: 192.168.0.101 Click OK button. Then click Deploy to Hardwear button It diplay build error like below:

=== Build (Elapsed: 44 sec) === The location provided() is either empty or does not exist The location provided() is either empty or does not exist Warning: Unable to add configuration ev3, error: Failed to open the configuration "C:\MATLAB\SupportPackages\R2015b\legomindstormsev3\toolbox\realtime\targets\ev3\registry\ev3.m".
