Converter isn't detected in Waterfox 64bits Puntuado con 2 de 5 estrellas

Video DownloadHelper + Converter in 64 bits : Waterfox and, I guess, recent nightly FF 13 64 bits I've not tried yet : the extension works OK but it doesn't recognize the conversion program although already installed It is recognized in FF 32 bits but in 64 bits, it considers the program has not been installed. (maybe it looks for it in the 64 bits programs).
