o3D samples can't run in localhost

I have downloaded the samples from Google o3d,but it can't run in my computer.The question like this:Even I install the o3d plug-in again and again, it always prompt me that I have to install this plug-in 开发者_Go百科when I visit the samples' website that I published in IIS 7.The IE7,opera and chrome has been tested, them are all the same. This is my first time to ask a question using English,so I hope it is clear to you.Thank you for any reply.

I have found the answer,

Find o3d/samples/o3djs/util.js and change:

o3djs.util.REQUIRED_VERSION = '0.1.42.4'; 

to

o3djs.util.REQUIRED_VERSION = '0.1.42.3';
