I was trying to run the echotcpip exaple after installing the Instrument Control tool box package, it was complaining and responding with the following message.

Error in tst (line 1)

echotcpip('on',4012)

When i tried the follwonig command

which -all echotcpip

I got the following response

C:\Program Files\MATLAB\R2017a\toolbox\instrument\instrument\echotcpip.m % Has no license available

But the ver command shows

MATLAB Version: 9.2.0.556344 (R2017a)

MATLAB License Number: 6XXXXXX

Operating System: Microsoft Windows 10 Pro Version 10.0 (Build 18362)

Java Version: Java 1.7.0_60-b19 with Oracle Corporation Java HotSpot(TM) 64-Bit Server VM mixed mode

----------------------------------------------------------------------------------------------------

MATLAB Version 9.2 (R2017a)

Instrument Control Toolbox Version 3.11 (R2017a)

MATLAB Compiler Version 6.4 (R2017a)

MATLAB Compiler SDK Version 6.3.1 (R2017a)

Parallel Computing Toolbox Version 6.10 (R2017a)

So what am I missing.

You are missing a license for Instrument Control Toolbox.

In some cases, especially with organizational machines, it is possible to install toolboxes that the user will not have a license to use.

I can tell from what you have installed that you are not using a Student or Home license, which makes it likely you are using an organization license.
