You will need to install the Desktop Manager program on your computer first. Then, you will need to install the handheld operating system installation file on to your computer that matches the operating system on your BlackBerry (you can find out your OS by going to Help > About).
Once that is done you will be able to use the Application Loader module in the Desktop Manager to install the BlackBerry Messenger.
