The x64-based versions of Microsoft Windows Server 2003 and 
Microsoft Windows XP Professional x64 Edition include a 32-
bit version and a 64-bit version of Microsoft Internet 
Explorer. Both versions of Internet Explorer are included 
to increase compatibility with existing programs and Web 
sites. The 32-bit version of Internet Explorer can host 
only native 32-bit ActiveX controls and other 32-bit Web 
page objects. The 64-bit version of Internet Explorer can 
host only native 64-bit ActiveX controls and other 64-bit 
Web page objects.

Interopability with existing technologies

The differences between the 32-bit and 64-bit versions of 
Internet Explorer can affect toolbar add-ins and Microsoft 
ActiveX controls. For example, 32-bit toolbar add-ins do 
not work in the 64-bit version of Internet Explorer. These 
add-ins include the MSN toolbar, the AOL toolbar, the eBay 
toolbar, and the Google toolbar. You can install 32-bit 
toolbars in the 32-bit version of Internet Explorer. 
However, the 32-bit toolbars will not appear in the 64-bit 
version of Internet Explorer.

For example, when you start the Setup program for the 32-
bit Google toolbar in the 64-bit version of Internet 
Explorer, the Google Setup program closes the 64-bit 
Internet Explorer window. The Google Setup program opens a 
new 32-bit Internet Explorer window when setup is 
completed. The Google toolbar appears in the 32-bit version 
of Internet Explorer, and the toolbar works correctly. The 
32-bit Google toolbar is not installed in the 64-bit 
version of Internet Explorer.

By design, the 64-bit version of Internet Explorer cannot 
host 32-bit ActiveX controls. Additionally, the 32-bit 
version of Internet Explorer cannot host 64-bit ActiveX 
controls.
