Can't install Norton 360
I recently bought a laptop, so I'm new to using it. Anyway, it came with a 30 day free trial of Norton, which I .activated. Today, it ended so I purchased the 360 version3. I downloaded it with no problem. However, after doing that, I received no further prompts. There is a 'Norton 360 Installation' icon on my desktop now, but every time I click on it, first I get the message that there's an unknown program that wants access to my computer. Then when I click to allow it to run, I get the message: Another installer is currently running. Help! I have no idea what to do next. I tried Norton live chat/help but there was an error trying to load that. Any ideas would be appreciated. Thanks!
