Internet Explorer 32 and 64 Bit Differences

Internet Explorer 32 bit and 64 bit Version Use

If you are running Windows 7 64 bit, you may have noticed that in the start menu there is a shortcut to Internet Explorer (64-bit).  If you are wondering what it is for, Ill try to give you some information.

From the Microsoft Knowledge Base:
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.

Some More Information:
If you experience problems when you use the 64-bit version of Internet Explorer, try to view the same Web site by using the 32-bit version of Internet Explorer. If the problem occurs in both versions of Internet Explorer, you must determine whether the problem is caused by a Web object or if the problem is caused by Internet Explorer.

To determine the version of Internet Explorer that you are running, click About Internet Explorer on the Help menu of Internet Explorer. If you are running the 64-bit version of Internet Explorer, the About Internet Explorer window includes
a 64-bit descriptor label. The 32-bit version of Internet Explorer does not show a bit-level descriptor.

Interoperability 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.

As you can see there are some differences between the two versions.  If something does not work as expected in one version, try the other.
