Change Embedded Browser on vSphere Client for a Web Based Plug-in

I am developing a Web Based Plug-in for vSphere that is only compatible with Internet Explorer 8+. When I try to run it with the embedded Internet Explorer in vSphere Client, it does not work.

My system's Internet Explorer is the 8, but when I check the browser version with a script, it is always says version 7 with document mode 8.0. I still do not know if the embedded browser is an Internet Explorer 7 or an Internet Explorer with forced Compatibility View.

I already used user agents such as <meta http-equiv="X-UA-Compatible" content="IE=EDGE" > to make sure to disable the Compatibilty Vie开发者_如何学Cw on IE. Besides that, I already disabled the Compatibility View in the IE options.

Question

Is it possible to set the browser embedded by VMware, update the Internet Explorer or prevent it to use Compatibility Mode?
