64-bit versions of Microsoft Internet Explorer 8 and 9 are certified with Oracle E-Business Suite. IE 64-bit will run the 64-bit JRE plug-in. You can deploy these 64-bit IE releases as desktop browser clients for your EBS 11i and 12 end-users running 64-bit versions of Windows 7 and Windows 7 Service Pack 1 (SP1).
How will this work?
By design Microsoft does not allow the 64-bit browser to be set as default on the desktop client. Launching IE from a 3rd party application will cause the default 32-bit version of the browser to open which is expected behavior.
