unity web players crashes when loading a game such as dead trigger 2 in IE and have to close browser windows 7, tried using firefox but even after i run the webplayer installer it still thinks its not installed? any help on this out there?
Web player is obsolete. You should use WebGL.
Just keep in mind that IE is not fully supported by WebGL and user would have to confirm to run the game, because IE lacks some features, but nobody cares about implementing them so it is going to be how it is.
Also, if you are on Unity4 and can not use WebGL, it is a bug and I still believe no one is going to fix it, especially since Web Player is obsolete and IE is obsolete too (Edge is the new browser).
