If you have bought Revo, you should have received at this moment an email containing the download links and registration info. Download the application and install it and use the registration info to activate the software. Load it from the desktop and then wait for the list to populate with results (applications installed in your computer). Identify the application you want to remove and then right click it and select Uninstall. If you want an aggressive mode, select the last option and wait for the finish message.
