Before you unsintall this, you can try to update the application to the latest version available. By doing this, some functionality errors might be fixed.
You can try to uninstall this software by regular way. To do that, close all programs, open the application's folder, drag to the trash the icon of the program and then empty the trash. Also, check if the application doesn't have an uninstaller utility. You can check the installer disc or the official website for it. However, if all this things aren't working, I recommend that you use CCleaner. This is an utility that will remove the application as well as all the related files that have been created by it.
