Error while trying to get connected to a server

Hi,

While using the matlab command ib = ibtws('',7496); to try to get connected to the software Interactive Brokers, I got this answer from matlab:

Error using actxserver (line 93)

Server creation failed. Invalid ProgID 'TWS.TwsCtrl.1'.

Error in ibtws (line 37)

x.Handle = actxserver('TWS.TwsCtrl.1');

Could you give me an answer of how to cope with this issue ?

have you enabled activeX and socket clients in the IB TWS settings?

Hi Roux,

This error indicates that the Trading Toolbox in MATLAB cannot establish a connection to the IB Trader Workstation ActiveX-based API. To resolve this error, first follow the troubleshooting steps mentioned in following MathWorks post: 

https://www.mathworks.com/matlabcentral/answers/272667-why-do-i-get-an-actxserver-error-when-trying-to-connect-to-interactive-brokers-trader-workstation

If after following the above post, you are able to get "success" message from Excel VBA and still getting connection error in MATLAB, then try following troubleshooting steps as a possible workaround.

1. Check if the anti-virus is blocking the application.
2. Uninstall IB TWS and API.
3. Delete all previous installation files and particularly delete following file (if it exists): "C:\Windows\SysWOW64\TwsSocketClient.dll"
4. Re-install stable version of IB TWS, and API from following link: http://interactivebrokers.github.io/downloads/TWS%20API%20Install%20971.06.msi

Hope this resolve the error!!
