Are you on Windows 8? You don't have to only install apps from the Windows Store... my cousin installed Firefox her very first day on Windows 8 by just going to their website... The latest versions of Firefox, Chome, Iceweasel, and Safari should work, as well as (possibly) Opera versions 12 and up. Internet Explorer explicitly does not support VisualEditor.

If you're on a tablet, installing outside the store be a different story (but it might be possible).
