Is Anistol (anisole) forbidden?

The "Installous" program is a tool whose permissibility is judged based on its use. If it is used to download permissible things, then it is permissible. If it is used for unlawful things, then it is unlawful. Thus, if it is used to download protected programs or programs that contain a Sharia-prohibited element, then it is forbidden. But if it is used for downloading what is permissible, then there is no harm in it.
