Can't apply hotfix due to applet error

I'm trying to apply this hotfix http://helpx.adobe.com/coldfusion/kb/coldfusion-security-hotfix-apsb13 -03.html but when I go to System Info > Update File, I get a JRE security related error. I've tried Chrome, Safari, FF on PC and Mac without avail. Is there any other way to apply the hotfix without having some stupid applet? UGH.  TIA
