After uninstalling, restart your computer. Then start Windows Explorer and see if there is still a folder with the name of the software under C:\Program Files. Be sure to check the Registry as well for remnants of Opera Installer. To do this, start "Regedit", then look under "HKEY_LOCAL_MACHINE" > "Software" for Opera Installer or the name of the producer. Always keep in mind that only a computer professional should ever directly delete entries in the Windows Registry.
