Upgrade an Existing License

If you're already a registered CSE HTML Validator user and your name and email is in our registered user database, then you may buy an upgrade. This page will tell you if you are already licensed for the latest version and how much an upgrade will cost if you are not already licensed for the latest version. To upgrade, you will need the email address that is in our database (this is usually the one that you registered with).

You can also upgrade from the standard to the professional edition.

Fast and Easy Online Buying

Buying online using a credit card is considered the fastest, cheapest, safest, and easiest way to buy and receive a registration key.
