SNES-Coop Not Working, even with Visual C++ installed

[ringtailedfox]

This issue is very similar to #1 but I do have Visual C++ 2015 installed.

The version of snes9x-rr I'm using is https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/snes9x-rr/snes9x-1.52-rr-r185.zip

The issue in particular is that when i try to load up coop.lua in snes9x-rr, I get this odd error:
error loading module 'iuplua' from file '.\iuplua.dll':
The specified module could not be found.

The file is present... I just don't know why it can't find or load it...

Maybe you are compiling 64 bit and iuplua.dll is 32 bit, or the other way around.

oh, i wasn't compiling it... i just copied over the /coop/ folder and ran snes9x-rr as instructed. i then tried intsalling Lua for Windows and rebooted... since then, every time i try to run coop, that causes snes9x-rr to crash.
