What C++ redistributable does Unity3D editor require?

Questions & Answers

There is a system that an engineer on my team is installing only the minimal software required to run Unity3D, due to various reasons.
Unity 2020, a recent version.

He uninstalled Microsoft Visual C++ 2010 redist X64 10.0.40219.

Now, it is throwing an error when launching Unity “The code execution cannot proceed because MSVCR100.dll was not found. Reinstalling the program may fix this problem.”

Does Unity 2020 require the C++ 2010 redistributable? Or what is the minimum version required?
Or is something else going on?

When I remove the DLL manually, Unity does not launch.

So assuming there is no way around it, the latest Unity in 2021 does require Visual C++ 2010 redistributable.
