Latest questions about "roxio recordnow music lab premier"

I have the CDRom of RecordNow9 but it won't install on my computer with Windows 10. Almost gets finished then it pops up with the message a 'missing certificate'.

I bought this program a few years ago as a CD. Am I able to download the current version and use by code that come on the CD sleeve or do I have to purchase again?

Can I use Roxio RecordNow Music Lab Premier 10.1 to record Pandora radio on my laptop?
