I think the docs specified to put the .dll parallel to the .exe file - which did not work. Putting the 'sqldrivers' or any other plugins subdirectory parallel to the executable is not specified, as I read it, but I can read it again.
If the site had a better search mechanism, I might be able to find things more easily. Searching for 'plugins location' gives me everything with 'plugins' and everything with 'location' in no particular order, which is not very helpful. I get better results with Google search.
