In order to offer a solution, it is usually necessary to understand how the system got into the state it is - hence the request for the method used.

'just downloaded it from the Internet' obviously didn't work for you, but it is very difficult/impossible to help using the information provided.

Re-check that the installation instructions you used are from a reputable source and are valid and recent. If they are, then double check that you correctly executed them.
