----DOWNLOAD ERROR NOTICE----


HTTP downloads using some web browsers may be limited to ~ 2-3GB
If you receive an error notice like: "Internet Explorer cannot display the webpage" or The HTTP header is invalid" you may consider trying another Web Browser. This limitation may not be obvious as some browser versions attempt to download the file and appear to do so successfully when in fact only part of the file downloads. These limitations have not been reported by users of:

FIREFOX

OPERA


----ARCHIVE ERROR NOTICE----

Older file compression utilities including the compression application packaged with some WINDOWS OS may not recognize large archives creating using 64 bit compression methods. Attempting to open archives over 3GB may result in a Windows error message stating the archive is corrupt. That is not correct.

Large archives may be opened using other ZIP utilities like:


7-ZIP


JustZIPit


WINZIP


ALZip


This is not an endorsement of any product, nor is it intended to be a comprehensive list of compression utilities capable of handling large archive files.
