This will open the application and depending on whether or not you've already got certain tools installed, you will be presented with different options.
Selecting Packages to Install
It should be fairly straight forward on what to do next, simply select which packages you wish to install plugins for.
The tools automatically detects the supported applications and where they are installed on your hard drive.
After you've chosen your packages, click Next and you should get a 'success' (or a 'fail' if something went wrong) on the installation of the plugins.
And that's it!
