> which I installed in SysWOW64
Generally it's not a good idea to manually put things in system folders.
Depending on the path ordering, Julia might be picking this copy up before
the version that's installed by Julia. Remove the libzmq dll from SysWOW64
unless you have some really good non-Julia reason for putting it there.

The package name on WinRPM isn't ZMQ, you'd need to do
WinRPM.install("zeromq"). Though when you do Pkg.build("ZMQ") that should
get run automatically.
