CSS HTML Validator Home/Pro/Enterprise 2020 (v20.04) is now available to all customers that have a valid 2020/v20 license.
IMPORTANT: The new 2020 release continues to be native 64-bit and requires a 64-bit OS. If you're still using a 32-bit OS then please let us know. We may be able to send you an unofficial 32-bit build.
If you have a previous 2020/v20 version installed (including 2020 BETAs), then simply install the new 2020 RELEASE version over your current 2020 installation to update it. All minor updates (like v20.00 to v20.01 and v20.01 to v20.04) should also be done in this manner.
If you have a version prior to 2020 (like 2019/v19, 2018/v18 or v17) then we recommend that you uninstall it first and then install 2020. The 2020 setup program should ask you if you first want to uninstall your old version and we recommend that you say 'yes' to uninstall the old version. However, if you have a reason to keep the prior version on your machine then you can do so and both versions should work (they will share some, but not all settings).
NOTE: When uninstalling a previous version, do not do a "full uninstall" when asked unless you want to start fresh and lose all your options and settings. If you choose not to do a "full uninstall" then many options and settings will be kept from your previous version and used in 2020/v20.

Hint: Load your current version and do an update check (Help->Check for New Program Version or Help->Check for Updates). This should open a browser window with your registration number and PIN number already filled out. Just select v20.0xxx and download.
IMPORTANT! A 2020 RELEASE key is required. 2019/v19 keys WILL NOT WORK with 2020/v20. Get your CSS HTML Validator 2020 key here.
