I have Google Chrome set as the default browser on my computer, but some programs are still opening Internet Explorer windows. Why is this, and is there anything I can do to fix it? I am using Chrome Version 23.0.1271.95 m, although I believe this is a Windows problem, not a Chrome problem.

Edit: I can disable IE through Windows, but when I do, the program which launches it throws a "Class not registered" script error. The following code is the script which launches it:

<!-- Script to enable drop down suggestions and link source file-->

//Funtion to open new window when any item is selected from suggested drop down
function callback(item) {

jQuery(function() {
    $.getJSON("*url snipped*",
        function(data) {
            $('input#suggestBox2').jsonSuggest(data, {maxResults:20,onSelect:callback});

What part of that causes it to open in IE, and is there any way to redirect it?

  • Please always include the operating system and versions of the software you are having problems with. – terdon Dec 4 '12 at 14:50
  • @terdon - Sorry, forgot that that might be important :) – SaintWacko Dec 4 '12 at 14:52
  • Thanks, what is really important is the Operating System since this type of problem often depends on the OS version (plus, not everyone uses windows, certainly not everyone here :) ) – terdon Dec 4 '12 at 14:56
  • Also, the version of Windows might be relevant ;) – Everett Dec 4 '12 at 14:57
  • @terdon - I know that well, I used Fedora for a while. It just slipped my mind for a moment. – SaintWacko Dec 4 '12 at 14:57

AFAIK some software using hardcoded option of which browser to open for page, and you cant change it even though you have setup some other browser then IE as default. Mostly these are some launchers go different games and some corporative software.

  • That's exactly what I'm having issues with: corporate software. Hopefully someone has a way to change it, though; a workaround of some sort. – SaintWacko Dec 4 '12 at 14:53
  • I think if you completely delete IE from system via components management(might be wrong name), and then OS will lauch your default browser due to unavailable IE – sanny Sin Dec 4 '12 at 14:55
  • I suspected I would have to do that. – SaintWacko Dec 4 '12 at 14:58
  • Mostly this "issue" because corporative software can be very specific and require something unusual, so developing page for only IE, would cost much less then develop page for all browsers. – sanny Sin Dec 4 '12 at 15:00
  • That's what I would have thought, but if I copy the URL into Chrome, it works exactly the same. – SaintWacko Dec 4 '12 at 15:02

Where is that code executed from?

If it's already running inside a browser, then window.open should open another window in the same browser.

There is no indication that that code should invoke anything but the standard browser or the host browser it is running in.

  • Hm... If it's a standalone application that uses the IE rendering engine (that may not be exactly how it works, but something like that), would it open an IE window? – SaintWacko Dec 5 '12 at 14:10
  • @SaintWacko looks like it is a program which has a built in browser window and these kind of things use the windows default browser like the one that you create using an AutoRun making program. Can you tell me which programs give this error? have you build them? – TechLife Dec 26 '14 at 13:31

If you don't use Internet Explorer for anything, you can disable Internet Explorer so that your programs do open up google chrome because that will be your only browser.


  1. Click the start button
  2. Type "Windows Features"
  3. Click on "Turn Windows features on or off"
  4. Scroll through the list and find the Internet Explorer box and uncheck it
  5. Restart your computer

Then it should be gone

  • Well, that disabled it, but now the program throws a "Class not registered" script exception where it would normally open IE. – SaintWacko Dec 4 '12 at 15:24
  • I've added the bit of script that does it at the bottom of my question, as it didn't format properly in a comment. – SaintWacko Dec 4 '12 at 15:38
  • I'm not really sure, I've never had the problem, I apologize that I couldn't help anymore. – JustinD Dec 4 '12 at 15:58
  • They must have done something different to force it to launch in IE. – SaintWacko Dec 4 '12 at 15:59
  • Saw this. function PopIma(img) { w=open(img,'hej','top=0,left=0,width=10,'+ 'height=10,toolbar=no,scrollbars=no,'+ 'resizable=yes'); } – JustinD Dec 4 '12 at 15:59

Since you've disabled IE via the Windows Features dialog, try the following. No guarantees it will work or that it won't break anything else; it's just something that suddenly occurred to me. As always, be careful while editing the Registry!

Open Regedit and navigate to:

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

Under that key, change the value of (Default) from:

C:\Program Files (x86)\Internet Explorer\IEXPLORE.EXE



Similarly, change the value of Path from:

C:\Program Files (x86)\Internet Explorer



i.e. the path to the directory where Chrome.exe resides.

Also navigate to the following key and make the same two changes:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\App Paths\IEXPLORE.EXE

Now confirm that the changes have worked by typing "iexplore" in the Run dialog. If Chrome starts up, all's fine. Now run the program, cross your fingers and see if it launches Chrome instead of IE. If it does, let me know and we'll celebrate! :)
