Windows 7: IE browser generates "Application not found" error if set as default.

IE browser generates "Application not found" error if set as default.

I'm running Win 7 (32bit) HP SP1. I'm having the same problem whether using IE8 or IE9.

If I set IE as my default browser I get an "Application not found" error whenever I click on a link which should open in a browser. Other browsers work just fine.

Makes no matter whether I use the IE > Tools > Internet Options to set IE as the default browser or Control Panel > Set Default programs I get the same error.
I am unable to use Default Programs > Set Associations to make IE default for HTTP, etc. because the IE icon is missing from the selection screens.

I tend to believe that restoring this icon is part of fixing the problem.

Google searches have led me to many suggested fixes (registry mods, etc.) but nothing has helped.

Does anyone have any idea how to fix this problem?

Dave, welcome to Sevenforums!

Try reseting IE. It will ask if you want to keep your settings: go to Internet options, click the Advanced tab, and click reset down at the bottom

Hi Dusty -

Thanks for the reply. Resetting to the defaults does not help.

I've even switched from IE9 back to IE8 and the problem still persists.

Alrighty, try an SFC scan: SFC /SCANNOW Command - System File Checker

Failing that, and if you have the right CDs as described within, try a repair install: Repair Install - to see just what this will change, read about it in the tutorial

Make sure your computer is virus free. Run your fully updated antivirus for a full scan. You might consider installing Malwarebytes along side it for a secondary full scan to make sure you checked everything.

Can you install all important updates for IE9?

Hi Dusty -

I've tried SFC and various virus checks to no avail. I don't really want to chance a repair install because nothing is broken except IE and it is only broken when selected as my default browser.

Things work fine if I use Chrome or FireFox as my default browser. IE also works fine except I must manually insert the url for live links found in emails, etc. if I want them to open in IE.

It's been this way for several months now and is only a minor annoyance, but I lie awake nights trying to figure out how to fix it!

Please tell me the name of your antivirus program and any other antispyware, etc. programs you have installed, including security-related addons.

Even if you have don this, please do again:
Go to Default programs and click set your default programs. Set IE as default. Go back to Default programs and click set program access and computer defaults. Expand Custom and make sure IE is selected, and it also has the check box to enable access to it.

Make sure IE isn't turned off in features:
Control Panel->Programs and Features->Turn Windows Features on or off

Understandably the repair install can be daunting, but it does work very well at fixing things, I tested it myself. If you need, you can print out the instructions. Doing it is completely up to you, but it may help your situation, if you have the right CDs.

Dusty asks: Please tell me the name of your antivirus program and any other antispyware, etc. programs you have installed, including security-related addons.

Dave replies: I'm running MSE, Windows firewall, Secunia PSI & WinPatrol full time. From time to time I use a web based virus scan whose name escapes me right now.

Dave replies:
Did all that once again - a rather odd thing happens when I expand "Custom" - if I select any browser button and come back later w/o making other changes the selection has reverted back to "Use my current web browser"???

I currently have three browsers installed - IE, Chrome and FireFox. I can change all the default browser settings from within each browser everything works except for the IE problem stated above.

Can you shed some light on this problem/symptom:

When I try to associate a program with HTTP, HTTPS or ftp protocols I can only select Chrome or Firefox - the IE icon is missing! When IE is the default Browser this screen says "Unknown application". Why is the IE icon missing? A registry error, perhaps? My gut feeling tells me that the problem won't be fixed until I get the IE icon to appear there.

Any ideas how I can get the icon to appear? Doing so might not provide a complete fix, but would be some progress.

Re: a repair install - the machine with the problem, my laptop, mirrors my desktop machine. I have highly customized the Windows 7 OS on these machines to my liking and use various tools to keep things in sync. I don't want to jeopardize things over this minor issue.

Haha, at first I thought this was an "I already told you that" thing. Sometimes I don't pay attention... that story is for another time...

Alrighty mate. Unfortunately, I have come to the end of my knowledge. I do believe that some of those customizations might have had a part in your misfortune. I also think all of your IE problems are interlinked. Windows 7 wasn't intended to be customized outside of its pre-built settings. You may have to live with this minor issue, as you say. I wouldn't be suprised if you come across some other complications in the future, not fully realized just yet. But, I wish you well, and am really sorry I couldn't help you further.

As an aside, I would be very careful of malware when downloading customizations off the internet. Cheers!

A process monitor log, run while attempting to open a link and then saved / zipped and uploaded will help.

Two simple things to try.

Start> In search box type Default programs> Enter> Set Programs Access and Computer Defaults> Select Microsoft Windows and click OK

If this has no effect, try creating a new user account and see if IE works normally there
