using onnxruntime without installing visual c++ runtime DLLs

[alexxthiery]

I am trying to deploy a (python) software that uses onnxruntime on a medical device that runs Windows 7. At the moment, it is not working because the Visual C++ runtime 2019 are not installed. I would like to find a way to not install these runtimes since that may create compatibilities issues (and it would potentially be extremely difficult to revert to the original configuration once the updated C++ runtimes have been installed since apparently some of the old DLL are being overwritten). I have tried to just copy the appropriate DLLs on the path, but apparently onnxruntime runs some additional checks.

Any suggestion?
