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 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:
Press the Windows key and start typing "command prompt". When Command Prompt appears, right-click on it and select Run as administrator.
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.
32-bit Windows operating systems:
copy "%userprofile%\desktop\TopStyle5.exe" "%programfiles%\TopStyle 5"
64-bit Windows operating systems:
copy "%userprofile%\desktop\TopStyle5.exe" "%programfiles(x86)%\TopStyle 5"
For best results, copy the above to your clipboard, then right-click in Command Prompt, then select Paste.
When Command Prompt asks you to overwrite TopStyle5.exe, then press y.
Delete TopStyle5.exe from your desktop:
Sorry, TopStyle is no longer available for purchase.
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 received from us when you bought TopStyle.
A public TopStyle support forum is available. However, the TopStyle forum is read-only and cannot be posted to because new support is no longer available.
