Can't run .bat (Batch Files)


  • I accidentally chose notepad as the default program to open .bat files when I needed to edit it.  Now I can't run batch files on Windows 7.  How do I run batch files again?

  • Hi Greg, we can manually edit registry or run the following tool to reset the association:

    Unzip the zip, double click the file, after importing the reg information, you can double click and run the bat file.

    Hope this helps!

  • Ran it but no difference. I am trying to start Outlook from a batch file. Here is my syntax:

    cmd /c "c:\program files\microsoft office\office12\outlook.exe"

    The response I get is

    'c:\program' is not recognized as an internal or external command, operable program or batch file.

    Given that it is in double quotes, not sure why Windows 7 suddenly doesn't recognize it?

  • batfix worked for me. UltraEdit had grabbed the file association for .bat and I couldn't get UltraEdit to release the file association. Thanks a lot for putting this together

  • It's the best and completely safe way to restore automated running batch files. No risk of system vulnerability like after installing unknown tools.
    Thanks ZERO Tolerance !!!

  • This did not work for me either. I tried manually deleting the registry, and also importing the .reg. Neither worked for me. It still opens in notepad.
