The download is a fully operational, 30 day trial version. You can register the trial version at any point during the trial period, or later, by ordering a license. Note that both the Keyboard Designer and the Runtime Keyboard will stop functioning after the trial period.

The files are zipped installation sets. You must unzip the Setup.exe program and then right-click it and select Run as Administrator to install. You must also use the Run as Administrator option to start the Keyboard Designer and/or Keyboard Control Panel when entering your license key. Also note that the Runtime Keyboard cannot be used during logon on Vista or later, but Vista and later have that feature built in. Other than that both the Keyboard Designer and the Runtime Keyboard will work as before on all Windows versions.
