Hello @ECSailingPVS,

Thank you for posting here in the Community. Allow me to step in and share some information about QuickBooks Desktop.

Fiat Lux - ASIA is referring to a one-time purchase of the desktop product. You'll need to purchase or have an existing 2021 version of QuickBooks to have a license key. You can use this during the installation of the program.

For additional reference, I've attached a link about the discontinuation policy, as well as some answers to frequently asked questions regarding the older QuickBooks versions: QuickBooks Desktop service discontinuation policy.

Drop me a comment below if you have any other questions about the Desktop version or if you need additional guidance. I'll be happy to help you some more.
