I tried with FIrefox but it's the same problem;
I also tried an offline deploiment but no much luck:(
The web player always say that a newer version of unity web player is required.
Any idea how i can disable the auto-updated.
And by the way my unity webplayer is the latest...
I'm having the same problem as you, I've done what most answers I've found said but it still repeats the same thing, I can't seem to find answers for chrome specifically though, I think it's most likely because most people use internet explorer, safari, or firefox as far as I know.
Try Usin Opera Unity web player works in opera very well and also if you have IDM then do not integrate it into opera and every thing will go well.
same problem was with me but after opera and disabling Idm for opera then I can play games which require unity web player.
Good Luck. Regards
