This version does not include the OpenSees solver. You need to install OpenSees by yourself. The easiest way is:

Download and install STKO

Download OpenSees 3.0.3 from this link OpenSees

Unzip the downloaded file and copy OpenSees.exe in "C:\Program Files\STKO\opensees\bin\OpenSees_303"

You are ready to go! STKO will automatically detect the OpenSees solver

Otherwise, if you have your own OpenSees solver located somewhere else (for example if you compiled your own version), you need to manually tell STKO where this solver is, running the Kits command in the Analysis Tool Bar. In this case don't forget that you also need to install HDF5 1.10.1 libraries in order to use the MPCO Recorder. If you don't want to install HDF5 you can copy the DLL files located in "C:\Program Files\STKO\opensees\bin\hdf5" in a location visible by OpenSees (for example the same folder where OpenSees is)
