can't run mplay on Windows, DLL doesn't load

[MarkNahabedian]

On MSWindows, when I try to mplay a MIDI file I get an error that a DLL can't be loaded:

using Mplay
  Activating project at `c:\Users\Mark Nahabedian\.julia\dev\RegistryCI.jl`
mplay("foo.mid")
ERROR: could not load library "C:\Users\Mark Nahabedian\.julia\packages\Mplay\zc7Lu\src\lib/libglfw.dll"
Access is denied. 
Stacktrace:

   @ Mplay C:\Users\Mark Nahabedian\.julia\packages\Mplay\zc7Lu\src\Mplay.jl:266
 [4] top-level scope
   @ none:1

I tried using regsvr32 to register the DLL, but it complains that

"the module ... was loaded but the entry-point DllRegisterServer was not found.

Make sure that ... is a valiud DLL or OCX file and then try again.

I suspect a problem with BinaryBuild's GLFW build. Could you try the following:

git clone https://github.com/JuliaMusic/Mplay.jl
cd Mplay.jl\src
set PATH=%PATH%;.\lib
julia Mplay.jl <your-midi-file>

Thanks. That worked.

Will see how to make this more convenient for the end user.

Could you try to change the ACLs of the required DLLs, e.g.

icacls .julia\packages\Mplay\rgPTE\src\lib\*.dll /grant Users:rx

This is only a workaround. Please replace rgPTE with your path.

I will have to automate it within the installation/build step.

[MarkNahabedian]

Thanks. That worked. If I try to run `mplay` a second time in the same Julia session though, I get ``` midi: cannot open MIDI output ``` and Julia exits.
