After trying this for hours I gave up, but came back to this today and found 2 issues. First, at least on my system, libzmq-v142-mt-4_3_4.dll cannot be renamed. Second, it also depends on api-ms-win-crt-runtime-l1-1-0.dll and api-ms-win-crt-heap-l1-1-0.dll which require Visual C++ Redistributable for Visual Studio 2015 installed.
