All versions of Browsium Ion and Browsium Catalyst
Microsoft Windows Server 2003 and Microsoft Windows 7 64-bit Editions include both a 32-bit version and a 64-bit version of Internet Explorer. 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.
If you have installed IE10 or later and then backed the browser version down to IE8 by uninstalling the newer one, the taskbar shortcut will now point to the 64-bit version of IE8 instead of the 32-bit version. This in turn will cause add-ons such as Browsium Ion and Browsium Catalyst to fail to load because they are not compatible with 64-bit IE8.
It is important that the 64-bit taskbar shortcut be changed to the 32-bit version. This can be done easily be deleting the shortcut on the taskbar, searching for Internet Explorer in the Start Menu, and then pinning the 32-bit version (the one that doesn’t say 64-bit in the name) to the taskbar.
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.
