factorio.exe - System Error

The program can't start because VCRUNTIME140.dll is missing from your computer.

I suspect the installer does not include necessary components.

That's a system file, if it's missing then there is something amiss with your OS, follow: https://support.microsoft.com/en-us/win ... d86e0ef4ca

As a developer with long Windows experience I can assure you that is not a system file, and it is not present in fresh installations of Windows.

Factorio seems to be built using MSVC compiler with an option that links to the C (or C++) runtime library dynamically. When you do that, your installer has to install the version of VCRedist corresponding to the compiler. See https://learn.microsoft.com/en-us/cpp/w ... -vc-redist

Alternatively the build options must be changed to link C runtime statically.

There seems to be something very wrong because we do build with the static linking option which means you do not require that file to exist in order to run the game.

It sounds like possibly something else trying to start when starting the demo requires it. Or something went very wrong when building the demo. I've never in the last 8 years of Factorio heard anyone have this issue.
