How do I change the browser mode to ie8?

Posted at: 2014-12-18 
I want to change the browser mode to ie8. because the Solution Bank for this maths AS edexcel cd doesnt work. I can open Live Text and click on the Solutions buttons but after it me whether I want to allow ActiveX blocked content (I click yes, which is what I always did before) it just gives me a blank screen...
