I thought you were asking about Windows, Matlab and Java. yes I have the trading toolbox installed Trading Toolbox Version 3.6 (R2019b) Thanks

Despair2000 commented 4 years ago

Uninstall the trading toolbox and try again.

softwarespartan commented 4 years ago

@purchagent the trading toolbox uses alternate version of java and puts a jar file in the class path that can't get in front of. A questionable design choice if you ask me but Mathworks can do whatever they want. Until can find a way to "quarantine" the trading toolbox, need to uninstall for IB4m to work.

purchagent commented 4 years ago

thank you both for your assistance uninstalling trading toolbox allowed me to connect

Can you share the error you’re getting. Also can you share the output of the ‘ver’ command.
