Did Bracket Trader open this page after an error? That means you have the wrong API version. Or, IB failed to register the API properly in your system.

Now, you can switch to the correct API version with just one click using the API Switcher program. You can switch to the API being used by your other programs, then install the version of Bracket Trader corresponding to the API so you can run both.

NOTE: You must install TWS first before you install the API for APISwitcher to work (API installed in the c:\jts directory)

An API (application programming interface) is the program provided by Interactive Brokers for connecting to their trading platform. Because they made several versions available, you might not have the correct version in your system for running the version of Bracket Trader installed in your system. You might also not be able to use all your favorite programs because some of your programs use the old version, some use the current version and some use the beta version.
