Installation Requirements

The 2020.10 versions of Launcher, CMOST AI, Builder and Results have the following minimum installation requirements:

– NET 4.7.2

– Microsoft Visual C++ Redistributables for 2010

– Microsoft Visual C++ Redistributables for 2013

– Microsoft Visual C++ Redistributables for 2017

These redistributables can be found in the “Extras” folder. The installer will attempt to install these redistributables if it doesn’t detect that they are already installed.

The changes included in this release are summarized below. For more detailed information, please refer to the appropriate “What’s New” and/or readme document(s) for the associated products. To view this document, install this release first, then go to “{Installation Folder}\CMG\{Product}\2020.10\DOC\”.
