How do I install 360 multi device on a Kindle Fire running Mobile Security Lite?
You cannot install the 360 program on mobile devices. The mobile device offering is the Norton Mobile Security. You need to go to the app store for your device and search for Norton Apps.
If you are trying to activate the lite version, look for a Settings or Configuration page, and see if you can see anywhere to register, or activate the product. Then enter the product key from your 360 Multi Device subscription.
