IEDiagCMD – Inbuilt Tool to Diagnose & Troubleshoot Internet Explorer problems

IEDiagCMD.exe is a small utility that generates logs requires to troubleshoot issues with Internet Explorer in Windows. It is typically located under C:\Program Files\Internet Explorer on a x86 OS install and C:\Program files (x86)\Internet Explorer on an x64 OS install and can prove to be a very useful tool while troubleshooting Internet Explorer problems.


To bring it up, just type IEDiagCMD.exe in start search and hit Enter. When you execute IEDiagCMD.exe you will see a black window that stays open for few seconds and then closes by generating a cab file on your desktop. Double-click and open the files and you will notice that it contains a few logs and files.


  • The first file we know it’s the CBS log that generates mostly after running a system integrity check (sfc /scannow).
  • The second file is Windows Update Log which would have you Windows update history and related information.
  • The third file is the Compatibility View (CV) list. If you want to know more about it check this MSDN article.
  • The next one is Branding log file that helps us in troubleshooting issues with IE
  • The next one Windows_panther_unattend.xml I believe  it an answer file generated at unattended install
  • The next two files are related information about you IE version etc. you can open and view it in Notepad.

Here is what my C__Program Files (x86)_Internet Explorer_signup_install.ins file looks like:

CompanyName=Microsoft Corporation
IE4 Welcome Msg=1

When you need support or help while troubleshooting  Internet Explorer issues in forums or from your IT support, it is a good idea to include this file with it so that it will  make the troubleshooting process easier.

Thanks to my eightforums co-member Bill2 for telling me about this tool.

    The tool itself crashes on my new HP notebook which came with Windows 8. A frustration, indeed, when you wish to troubleshoot and the troubleshooter is the problem. Also, because the tool is called iediag , searching on the web to learn about known issues with it and possible fixes is impossible. All information I have found thus far, speaks to the logs the iediag tool creates,everything about IE issues, nothing about how to remedy iediag application failure. Help!

    funny thing is my IEDiagCMD.exe is in my program files not program files (x86). I have windows 7 ultimate 64 bit. should I move it (drag-drop) from program files to program files (x86)?
