Why can't I download the detection program software?

Last week I asked this questions while trying to download the newest version of yahoo messenger. yahoo sent me a link in order to help me to download messenger and it worked. Unfortunately, now I'm getting a message that I need up update software from the detection program and it's failing when installed. I cannot get past the second request for running a program. I'm not sure if it has to do with Windows Internet Explorer or not. I usually use Verizon Yahoo Broadband browers and when I start to download the Detection Program Software it goes to Windows Internet Explorer.
