Upgrade

Please allow up to one US business day to process your upgrade before receiving your new registration information.

Did you know that when you purchase an upgrade for CSE HTML Validator Professional that you receive one year of free major upgrades? For CSE HTML Validator Standard you receive 60 days of free major upgrades. Minor updates are always free.

Simply enter your email address in the form below and choose the correct options. The email address you enter should be the email address that is in our registered user database which is the original email address that you used to register CSE HTML Validator (unless it has been changed).

If the address in our database is not your current or valid email address, then you can still order the upgrade immediately, but you will have to update your email address so that your new registration key can be sent to the correct email address.

If you have a registration problem that needs human attention, then please contact us.
