Sometimes when you try to install your Norton security product, you get an error “8504, 104” and your installation gets failed. Doesn’t worry this is very common issue that lot of Norton users come across, and you can definitely deal with this issue very easily. First make sure that you do not have any other Norton family product installed in your device and if it is there then please download and run Norton Remove and Reinstall tool. This is a free tool available on Norton website. If you want to know exact process of downloading and running it then dial us at 0808-101-2159 Norton Customer Care UK.
After running this you also need to uninstall any other non-symantec security product as they can cause conflicts later on in installation. Once this is also done, then update your windows graphic driver as outdated driver can also cause the issue. In case you get stuck at any point then dial us at Norton Support Number UK for advanced assistance.continue reading
