Chinese Text Analyser is supported on all versions of Windows from Windows XP (Service Pack 3) onwards. Native versions are also available for macOS and Linux.

You can download the latest version here.

Once downloaded, double click the install file exe and follow the prompts.


If you are upgrading from a previous install, it is safe to reinstall over the previous version. All your configuration settings and vocabulary will be preserved.

By default, Chinese Text Analyser will install itself in Program Files and you will need to give the installer permission to write files to this location.


Click ‘Yes’ to give Chinese Text Analyser permission and continue with the installation.

Portable Installation

You can also install Chinese Text Analyser as a standalone program capable of running from a USB drive or similar.

To do this, first install Chinese Text Analyser to your location of choice. Then browse to the install folder, right-click on cta.exe and choose Create Shortcut.

Now right-click on the shortcut, choose properties, and then in the Target field add the text --portable to the very end of the target.

When you run Chinese Text Analyser from the shortcut, all program data, configuration settings, and vocabulary will be saved in a sub-folder of the installation folder.


The portable feature is only available if you have purchased a licence, and will not work with the free trial.
