I just bought Lightroom 6 from best buy. Used the registration number to download the serial, downloaded Lightroom, have it installed, but the serial won't validate. It continuously says to connect it to the internet, which I am, and never goes past that. I'm registered the serial onto my account, but I still can't validate it on my computer.
Is there something going on with my download? This is the second time I've done it. Can I mod something in my computer to let it register an internet connection?
If you are using Windows Machine you can try two steps to fix it.
1. Reset the Internet Explore settings
2. Reset the hosts file refer: https://support.microsoft.com/en-us/kb/972034
