NOTE: TopStyle was not developed by, and is not supported by, the makers of CSS HTML Validator.
TopStyle development and support has ended but you can still download and buy TopStyle.
TopStyle questions can be posted on the TopStyle online forum (but there is no developer support there either).
You can download the TopStyle 18.104.22.168 setup at the Internet Archive.
Then please download the latest TopStyle hot-fix:
Bug: Find/Replace in Files (Shift+Ctrl+F) might mistakenly select an incorrect line (and column) number when a match has been found in a UTF8 document. Fixed.
Bug: when you validate a HTML5 doc with the W3C validator, then the following error appears: HTTP Error 12168. Fixed.
Windows 10 and newer systems:

On older systems:
Click Start (or equivalent), and locate the Command Prompt menu item (it might be buried deep inside Accessories under All Programs). Right click on Command Prompt. On the pop-up right click context menu, select Run as Administrator.

The demo you download(ed) is also the registered version - there are no deliverables. A license key is what will unlock TopStyle from demo mode and allow you to use it without nag screens.
You don't need to download another version, you only need the license key. For best results, copy-and-paste the license key from the e-mail message you receive from us.
There is no physical delivery - our e-mail message constitutes the end of the transaction.
We have free public TopStyle support forums available.
You'll need to create a forum account before posting a new message or replying. The VIP code you’ll need to create a forum account can be found on the CSS HTML Validator Support Page.
If you cannot use the web-based forums, please send us an email instead. Keep in mind that since the web forums are our preferred channel for providing support, response time for emails is typically longer.
