Run \wsmith7\wordsmith7.exe to get started. You will be asked to register. Otherwise WordSmith will go through its paces as a Demonstration Version.
Upon receipt of the registration code, run WordSmith Tools. If you have only just installed the registration program will start up automatically. If not you can run \wsmith7\WSRegister7.exe. or find it in the Utilities section of the Controller.
If you make a mistake and your registration fails, you can try again. You can get a more recent version at the WordSmith home page.
To un-install, just delete all the files in your \wsmith7 folder. Your data may be in sub-folders of \wsmith7 or in sub-folders of your Documents\wsmith7.
