I need to run the 32 bit version of Windows Internet Explorer 11 for a specific app. But my OS is 64 bit. How do I specifically do this? Is it even possible? Thank you!

  • The default version of IE already is 32-bit – Ramhound Mar 2 '15 at 0:56

Your OS, being a 64 bit system, is able to install and execute both 32 bit and 64 bit applications. By default, Internet Explorer is executed using its 32 bit version.

Usually, the paths of Internet Explorer are:

  • 32 bit: C:\Program Files (x86)\Internet Explorer\iexplore.exe
  • 64 bit: C:\Program Files\Internet Explorer\iexplore.exe

IE 11 is 64 bit framework, on Windows 7 64 bit if you dont enable Enhanced Protection Mode in Advanced Settings>Security it will always run in 32 bit mode

    @DavidPostill: doesn't work for me. Unless that setting is changed, choosing "Internet Explorer (64-bit)" launches 32-bit IE. (Actually both a 64-bit process and a 32-bit process are running, but it seems to be the 32-bit one that I'm actually interacting with. For example, without turning on that option, I couldn't use the 64-bit Java plugin.) – Harry Johnston Mar 23 '16 at 22:55

    ... and if I do turn on that setting, I get the 64-bit IE even if I launch the 32-bit one. – Harry Johnston Mar 23 '16 at 23:00

Win 7 uses the 32-bit version of IE by default. However, if you want to be absolutely sure, just create a shortcut and add C:\Program Files (x86)\Internet Explorer\iexplore.exe as the program to call.

If you've executed "C:\Program Files (x86)\Internet Explorer\iexplore.exe" and still don't see 32-bit iexplore process in task manager, check your IE plugins. In my case there was iMacros 64-bit plugin installed. Somehow it prevented IE32 from running end started IE64 instead. After uninstalling the 64-bit plugin I was able to start IE32.
