iTunes- Error 1606

OKay, so you had me try to download itunes and I did try. When it did start to download it was checking for something on my computer and gave me this error- Error1606: Could not access network location bin. Then when I closed the download is said Error: -1603 fatal error during installation. I'm sure the second one was because I closed it, but I'm not sure about the first one. Thanks for your help, it's appriciated.

Thanks-
