DLL is missing from your computer

Question

Hello.
I have a project that was generated from the Import Shared Library Wizard.  The C++ project (which I did not write) has dependencies (OpenCV dll's).  When I try to run one of the VI's I get an error that says "opencv_core245d.dll is missing from your computer.  Try reinstalling ... " 
So, I do have that DLL.  Where do I need to put it so that LabVIEW knows it exists?  I tried Windows/System32 to no avail.
Solved!

What did you do to get the DLL working?  -- In case someone encounters a similar issue.
Also, I cant test this right now cause I am on a Mac, but if I recall you need to set the DLL and a function before the Call Library Function Node will be runnable.  So perhaps it selected the first (or only?) function name by default after your entered the DLL into the Call Library Function Node, but required you to confirm a function before proceeding.  Often you need to change the parameters or return value anyhow, so perhaps that's also required (viewing the tab and verifying the default Voids are okay).
Is this an issue at all?  Or were you just confused by the way it happened?

EDIT:
As long as you can follow steps similar to this guide below, you should be in business.  As to why it wasn't runnable before completing all these steps, that I am unable to answer since I have only used them a few times:
