TopStyle Information

TopStyle development has ended but you can still download and buy TopStyle.

NOTE: TopStyle is not supported by AI Internet Solutions LLC, the makers of CSE HTML Validator.

Download TopStyle

You can download the TopStyle setup at the Internet Archive.

Then please download the latest TopStyle hot-fix:

  1. Download the latest 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.

  2. The download is a zip file, not a true install. Unzip this file on your desktop.
  3. Click Start, and locate the Command Prompt menu item (buried deep inside Accessories under All Programs). Right click on Command Prompt. On the pop-up right click context menu, select Run as Administrator.
  4. Enter this into the Command Prompt:

    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 overwite TopStyle5.exe, then press y.

  5. Delete TopStyle5.exe from your desktop:

    del "%userprofile%\desktop\TopStyle5.exe"

Buy TopStyle

You can buy a new TopStyle 5 license or buy an upgrade from TopStyle 4.

After your purchase, you will receive an e-mail message with a license key from us.

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 (if you don’t have one already) is 7338270105.

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.
