[erlang-questions] WX Failed loading "wxe_driver"

Pretty sure this a crazy "Program Files" path thing. Windows still isn't 
too smart.

Your easiest bet is to reinstall erlang in a path without spaces in the 
name. When I was on windows I would choose to install to e.g.:
"C:\Erlang-R15B02"

...rather than into "C:\Program Files\...".

I ran multiple versions like this and I strongly suspect that the space in 
the path is the issue for the failed driver load (yes, even though it says 
"PROGRA~1").
