where to add web player playback engine in unity folder???

I have recently downloaded Unity 5.5.2f.

While completing space shooter tutorial, I realised that unity download assistant didn’t contain the web player playback engine…

I manually downloaded the web player from Unity Real-Time Development Platform | 3D, 2D, VR & AR Engine , but i don’t know where to place it in the unity installation folder…

Can anybody tell me, please…!!!

The webplayer is no longer supported. Try the WebGL option instead.
