Regarding the real time reading/displaying of the adc values of tms320f28027 on the simulink scope and how should i use the RTDX

Respected Sir,

                         I'm unable to display the adc values on the simulink scpoe with RTDX as i'm new to the simulink and ccs environment. after surfing for help I tried to find a command called

>> rtdxtutorial

but when i tried to excute in the matlab window 

below are the errors I observed

>> rtdxtutorial
==================================================================
The RTDXTUTORIAL is an example script intended to get the user
started with the RTDX.

A simple target DSP application is loaded and run on the target
DSP, and data messages are transferred via RTDX between the host
application (MATLAB) and the target DSP. The tutorial writes
integers 1:10 to the target DSP. The target DSP takes the array
of integers, increments it by 1, and writes the resultant array
to the host. This action is performed 20 successive times, with
each iteration incrementing the previous array result by one.
The 20 messages are read using various output formats.
==================================================================

Error using Link.ccssetup/Connect
Cannot start CCS application (COM error ID: 0x80040154).
Verify that your CCS software is installed and configured
properly.

Error in ccsboardinfo (line 68)
ccssetup.Connect(); % Connect to CCS Setup

Error in getNumTargetsInCcsSetup (line 7)
setupinfo = ccsboardinfo;

Error in selectBoardProcNumbers (line 13)
numTargets = getNumTargetsInCcsSetup;

Error in rtdxtutorial (line 42)
[boardNum,procNum] = selectBoardProcNumbers;

so how can i correct the very  starting error (COM error ID: 0x80040154) as it say LINKCCSSETUP error, is their any linking file missing and the ccs version i'm using is 

CCSv6.1.1.00022
