Virus Removal Tool

I bought Mcafee antivirus and when i put the disk in it won’t read. The disk works just fine on my mom’s computer. I had windows live onecare before but I uninstalled it thinking that was why it wouldn’t read the disk. I called Mcafee support and they told me to get a new disk so this is the second one with the same problem. Any ideas on how to get this to install?
yes I have already cleaned the disk drive,
