I would like to install different MySQL versions on Windows. I have a MySQL 5.5 running, and I want to install a MySQL 5.7 to debug compatibility issues of a program I am working on. Both installations should stay side at a side, may have their own databases (it’s OK to start with an empty 5.7) and I am happy to run or stop the one or other from the Services control panel manually. The nowadays MySQL installer - community wants to upgrade my existing installation and, unlike explained in this article, does not offer another option to install the versions side to side. All I found was a rant confirming my problem, but no real solution. If it requires me to install it manually, I need detailed instructions. In my case, default setup (default port) is sufficient, because I don’t need to run both instances the same time.

This is not so obvious but using the "MySQL installer", you need to run it, then click on "Cancel" and a new window will appear, letting you install new elements. You can then select the version(s) of MySQL that you want to add to your system.
You don't need it but if people want to run several instances at the same time, they need to choose a different port for each installation.
Use Dockerized mysql and you can run as many mysql versions you want on different ports.
