Unity Web Player and Java?

I have a customer that has an old version of Java (it is Java 6 and they can’t update it). When they try to launch my Unity Web Player content they are prompted by IE 10 with this message:

Java™ was blocked because it is out of date and needs to be updated.

I tried setting enableJava to false in the UnityObject configuration but that didn’t seem to help. The application works fine for them if they ignore the message (Unity Web Player is already installed on the machine).

Does anyone know why this message would appear and how I might be able to remove it? Does the Unity Web Player require Java (it doesn’t seem to since it works for me when it is disabled)?


I downloaded the UnityObject2.js file and edited it to turn off any Java installation functionality (then linked to my local version instead of Unity’s), that seemed to help.
