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.

Both versions of Internet Explorer share the default home page, the
Favorites menu, and the Temporary Internet Files folder. By default, the 32-bit version of Internet Explorer runs when you start the browser from any one of the following locations:
- The Quick Launch toolbar
- The desktop
- The Start menu
- A hyperlink or a file type that is associated with Internet Explorer
To start the 64-bit version of Internet Explorer, click
Start, and then click
Internet Explorer (64-bit). You can also add desktop and Quick Launch icons to start the 64-bit version.
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.
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.
Default settings and storage
Both versions of Internet Explorer use the following folders:
- Temporary Internet Files are stored in the \Documents and Settings\profile\Local Settings\Temporary Internet Files folder.
- The history list is stored in the \Documents and Settings\profile\Local Settings\History folder.
- The favorites list is stored in the \Documents and Settings\profile\Favorites folder.
Note profile is the folder that contains your account folders.
Additionally, both versions of Internet Explorer use the same default home page, security settings, and pop-up blockers.
You can open a Web page that was saved or copied from either the 32-bit version or the 64-bit version of System Monitor in both versions of Internet Explorer.
