Question New input system not installing properly

I have 2 projects, both of them use the new input system. Project A works fine, but project B doesn't respond to any input. Both have the same configuration, they both have the same input actions, and basically the same code. The only difference is that on project B I see this in the project settings window, which makes me think something wasn't properly installed.

 

That is about the OLD input manager (Input.GetKeyDown....blabla). It has nothing to do with the InputSystem, which is the next in the column on the left (next down).
If you read the text, it just says that you switched to the new Input System (only), so the old one won't work.
You can choose which one to use in the Player Settings (use new, use old, or use both).

 

OK, I understand.... anyway, the problem was solved when I copied the project setting from the other project.
