JQuery and Royal Slider

Hi, My client is running the Royal Slider plugin on their site. I did not know it but apparently jQuery 2.0 no longer supports IE 6,7,8. So the slider does not show up at all in these browsers. Apparently you can put a script in that uses conditional comments so it will work in the older versions. This is the code from the jquery site.
<!–[if lt IE 9]>
<script src=”jquery-1.9.1.js”></script>
<![endif]–>
<!–[if gte IE 9]><!–>
<script src=”jquery-2.0.0b2.js”></script>
<!–<![endif]–>

My question is what file do I add the code to?

Thanks.
