- Running the Windows version of the API installer creates a directory “C:\TWS API” for the API source code in addition to automatically copying two files into the Windows directory for the DDE and C++ APIs.
- It is important that the API installs to the C: drive, as otherwise API applications may not be able to find the associated files.
- The Windows installer also copies compiled dynamic linked libraries (DLL) of the ActiveX control TWSLib.dll, C# API CSharpAPI.dll, and C++ API TwsSocketClient.dll.
- Running the API installer is designed to install an ActiveX control TWSLib.dll, and TwsRtdServer control TwsRTDServer.dll.
- The TWS API is only available through the interactivebrokers.github.io MSI or ZIP file. Any other resource, including pip, NuGet, or any other online repository is not hosted, endorsed, supported, or connected to Interactive Brokers. As such, updates to the installation should always be downloaded from the github directly.
