If you live in the U.S. or Canada and want a browser with the latest encryption capabilities, download the 128-bit version of Internet Explorer 4.0 for Windows 95. What do 128 bits give you? The highest level of protection possible whenever you use credit cards or make other financial or confidential transactions over the Internet. When you use the 128-bit version of Internet Explorer in a secured connection with a bank, brokerage house, online merchant, or anyone else who has 128-bit capabilities, the information in the exchange is scrambled into the toughest-to-crack code available in the industry today.

Why just the U.S. and Canada?
Microsoft and other companies want to provide 128-bit protection to customers worldwide, but are currently prevented from doing so by U.S. law. That's why the main version of Internet Explorer normally downloaded on this site comes with 40-bit encryption capabilities, which U.S. law does permit us to distribute worldwide.

How do I get the 128-bit Version?
To download the 128-bit version of Internet Explorer 4.0, you must first install the 40-bit version from the Internet Explorer 4.0 download page. Once you've successfully installed the 40-bit version, download the 128-bit update from this page to run the 128-bit browser. An added step in the process will determine if your computer is registered in the U.S. or Canada before allowing you to continue. You must also agree to a list of conditions regarding use of strong encryption before you can download the product.

Once you have installed the Internet Explorer 40-bit Version, you can upgrade to the 128-bit Version by installing the following: Internet Explorer 4.0 128-bit Version for Windows 95
