Unity 2017 empty build folder!

Unity Engine
1

Hi,
Just upgraded to U 2017.
Now when I create a build of a scene the destination folder is empty. I get no error messages and I create the build in exactly the same way as I created them using Unity 5 but the build folder remains empty.

I even created a brand new project and created a basic scene with a plane, light, and camera and tried to build that and again the destination folder remains empty.

I create WebGL scenes.

Can anyone offer any help or insight?

thanks

Tried reinstalling 2017 but still, WebGL is not working. Could this be a bug?

Build using WebGL but on completion, the destination folder is totally empty. No files are created.

Help!
