During installation of your Roxio software, you get an error stating, "Can't connect to the Internet. Please check your connection and try again".
This happens even though you obviously have a good Internet connection.
Your antivirus or firewall could be configured to block modifications done to your system, such as registering components required to successfully install the software.
You will need to temporarily disable your antivirus and firewall software until your Roxio software has been successfully installed.
