How Does Windows Manage DLLs in Cache.

Let me explain this question.

I have two programs installed AppA and AppB. Both use DLLs with the same name, but those DLLs are actually different. The DLLs are in the program directories of each program (which are non-system folders)

I understand this is bad programming practise, however these are bought applications so I have no control in the matter.

My Question.

When AppA is running in memory and AppB is fired, Will Windows Manager use the DLL in Memory (since it has the same name and is in cache), or will it pull in the one from the program directory as it would if neither AppA or AppB was running?

Just for reference. The issue is with 2 bought apps using Powerbuilder 6 dlls with different build numbers. I am wondering if there is a potential for conflicts if both applications are running at the same time if one of the apps uses the wrong dll.
