Failed to build WebGL game

I am new in this and I was trying to understand how worked the built so I did the following:

1. Make a new project, 3D.
2. Switch platform to WebGL.
3. Build and select a new folder for the build.

After a while, I got this:

Code (Log):

1. Failed running "C:\Program Files\Unity\Editor\Data\PlaybackEngines\WebGLSupport\BuildTools\Emscripten_Win\python\2.7.5.3_64bit\python.exe" "C:\Program Files\Unity\Editor\Data\PlaybackEngines\WebGLSupport\BuildTools\Emscripten\emcc" @"C:\Users\MYUSER\DOCUME~1\PROGRA~1\Unity\THELAS~1\Assets\..\Temp\emcc_arguments.resp"
2.  
3.     stdout:
4.     stderr:ERROR:root:C:\Users\MYUSER\Documents\Programación\Unity\The Last Tower\Temp\StagingArea\Data\Native\build.bc: No such file or directory ("C:\Users\MYUSER\Documents\Programación\Unity\The Last Tower\Temp\StagingArea\Data\Native\build.bc" was expected to be an input file, based on the commandline arguments provided)
5.     UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

Then this:

Code (Log):

1. Exception: Failed building WebGL Player.
2.     UnityEditor.WebGL.ProgramUtils.StartProgramChecked (System.Diagnostics.ProcessStartInfo p) (at /Users/builduser/buildslave/unity/build/PlatformDependent/WebGL/Extensions/Unity.WebGL.extensions/ProgramUtils.cs:48)

8.     UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

And finally, which is the most strange, I got this:

Code (Log):

1.     Build completed with a result of 'Succeeded'
2.     UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

But the output folder is empty, and just to be sure, the project folder doesn't have any new file. So... nothing happens, What I am missing? How can I fix the error?

It's my first time using Unity so maybe I had forgotten to do something, but no idea. If I try with another option (like PC), it works.

My project was empty, I mean, I tried to build an empty project to know how much sized (mb) the base of any project and I found that it produces an error. I also tried to export it but first adding a few cubes (nothing of scripts, just cubes) but also didn't work.

PS: I wasn't sure where to post this, it's also my first time in the Unity forums

 

I've just discovered that Unity doesn't support special characters as `ó` so I change that to `o` in my project folder.
