How to Run Internet Explorer in Both 32-Bit & 64-Bit on the Same Computer
64-bit versions of the Windows operating system include two separate installations of the Internet Explorer Web browser. The first directory contains the standard 32-bit version of the browser, and the second is a 64-bit version. While the 64-bit version of the browser may operate more quickly, many plug-ins and extensions do not support it. As a result, the 32-bit version is usually set as the default Web browser on Windows. If you would like to run both versions, you can simply create a shortcut to both on your desktop. This allows you to easily identify each one, and quickly run them concurrently.
Click your "Start" button. Type "Internet Explorer" in the Search field. The search results list will display multiple results for Internet Explorer. The first result, which is "Internet Explorer," is the 32-bit version of Internet Explorer, and the second result, which is "Internet Explorer (64-bit), is the 64-bit version of the browser.
Right-click "Internet Explorer," and click "Send To, Desktop (Create Shortcut)." This places a shortcut icon to the 32-bit version on your desktop. Right-click the new icon on your desktop, and click "Rename." Change the name to "Internet Explorer (32-Bit)."
Click the Windows "Start" button again, and type "Internet Explorer" in the Search field. Right-click "Internet Explorer (64-Bit)," and click "Send To, Desktop (Create Shortcut)." This places an "Internet Explorer (64-Bit)" shortcut icon on your desktop.
Double-click the "Internet Explorer (32-Bit)" you created, and then double-click the "Internet Explorer (64-Bit) icon. You now have both versions of the browser open at the same time, and can easily launch each one from your desktop in the future.
