How to find out from the Windows registry where IE is installed?

Question

I can find out where Firefox is installed as follows; query this key to get the current version:

HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Mozilla Firefox
    CurrentVersion

... then query this key to get the installed path (where "nnn" is the version number obtained above):

HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Mozilla Firefox\nnn\Main
    Install Directory

But I can't work out how to find where IE is installed. What key or keys will work on Windows XP, Windows Server 2003, and later?

Solution 1

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\IEXPLORE.EXE

Solution 2

IE is included in Windows Features. Every windows operating system (XP and later) have IE installed by default. And the installation directory is always:

%PROGRAMFILES%\Internet Explorer

Is there any risk of this path being localized?

Sorry, I'm after the installed location, not the version number.

Works in Win 7 and Win XP and invulnerable to localisation issues.
