Why do I get an error when trying to create a ROS2 node on Windows 7?

I am trying to create a ROS2 node on a Windows 7 computer, but I get the following error for my model containing a ROS2 Subscribe block

MATLAB System block <path to Source Block> error occurred when invoking 'setupImpl' method of 'ros.slros2.internal.block.Subscriber'.
Caused by:
Unable to launch Simple server: Unable to launch
<matlabroot>\toolbox\ros\bin|win64\libmwros2server.exe
because: Unable to launch Simple server: Unable to launch server: initialization failed

I have used a similar model for ROS1 and I am able to build and run the resulting code within a ROS1 environment.

Windows 10 is the only Windows-based compatible platform for ROS 2, as you can see in the following web page:

https://docs.ros.org/en/foxy/Releases/Release-Bouncy-Bolson.html

As this is a ROS2 requirement, the only option is to upgrade your operating system to a more recent one. You can also consider using a Linux / Mac-based platform or a virtual machine.

If you encounter the above error message on Windows 10, please see the following MATLAB Answers Post:
