According to the readme.txt file provided in standalone OpenSees folder for both windows and mac, it is written that the folder should have corresponding MCRInstaller.dmg or .exe files. However, the MCRInstaller with version 7.13 is not there.
From the website of MATLAB, the latest version is available and not the compatible one. Can you please provide the correct MCRInstaller so that we can run OpenSees navigator?
The latest version of OpenSees doesn’t require MCR7.13. I switched to the latest version and downloaded MCR 9.6 (corresponding to Matlab 2019a) and it is working.
