Windows 10 - "this app can't run on this PC"

Hi,

I've been trying to install Norton Internet Secuirty 22.0 on Windows 10, but it won't let me. Every time I try I get the message: "This app can't run on this PC". I was able to install Internet Security 2015, but it won't accept my license key (Internet Security 2014). I thought version 22.0 was supposed to be compatible with Windows 10. Is there any way to install it on Windows 10 or do I have to purchase another license for Internet Security 2015?
