WebGL Build Errors

Unity Engine
1

Apologies for long error message, I’m getting this error when trying to build using WebGL, any help would be appreciated. as this has been for all games made during course. Side notes:I have the most updated unity, i’ve tried running as adminstrator, Api compatibility of both 2.0 and 2.0 subset and also reinstalling unity:

Do you build with Win7 x64? There i got the same errors (i think so, didn’t read every line of the message ;)). Building in Win8.1 worked. Its a Unity 2017 bug i guess.
