The code execution cannot proceed because python37.dll was not found

Question

I have a piece of code in C++ into which I am trying to include the Python.h library in order to manage the GIL (to speed things up). Despite adding the proper includes, libraries and path addresses (I am using Visual Studio 2019), I still obtain the following error message:

As far as I know, I correctly added the address of the DLL in the $PATH for this project, as shown:

What am I forgetting here?

Does dragging the dll into the VS project folder resolve this? — ZWang, Nov 16 '22 at 05:38
@ZWang: that worked, although I wish I didn't have to do that. — patrick2016, Nov 16 '22 at 05:57

Are you running this program in release mode? After switching from debug to release, the project properties of debug mode will not be inherited, so it is necessary to reset the project properties.

You could also try to place the dll file in the .exe directory or write the dll path into the project properties.

At the same time, it is also necessary to check whether the dll file is accidentally deleted by the antivirus software.

I made sure that the project properties applied to all configurations, yet that didn't work. Copying the .dll into the VS project folder actually fixed it. – patrick2016 Nov 16 '22 at 05:59
@patrick2016 Yes, I mentioned the method in the second sentence. – Yujian Yao - MSFT Nov 16 '22 at 06:13
