WINDOWS 10 Error = 126 (Unable to load mono library from...)

This error is not uncommon and every reference to it seems to be solved by installing the c++ redistributable. Unfortunately I have a friend who I'm trying to have play an alpha of a project of mine and when he runs the game he gets this error, when he tries to install the package he is told he has a newer version installed. He is prevented from ever launching my program. I have another friend who runs windows 8.1 who was able to the .exe without issue, so I'm certain it can work.
This seems to be the end of the documentation I can find, the mighty Google has failed to, that I can sniff out, provide an answer to this problem. Hopefully someone here may be able to help...

 

Rather than pull this to hide how stupid I was, I'm going to reply to it and hope that maybe if anyone makes the same... "newb" mistake that this helps them find their answer before making a fool of themselves by posting like I did. Turns out this problem is rather simple, Win10 is x64, when I was building the .exe I was failing to select x86_64. An important detail.
So I feel like a fool, but problem solved! All I had to do was build the game as x86_64 and it worked fine (after some strange .rar extraction problems which are likely unrelated...)
