CMD not running a batch file when I double-click the .bat file

Normally, double-clicking a .bat file's icon (or a shortcut to the same) should open a command processor window and run that batch file there.  Now the command processor window opens, but the batch file does not run.  (But the batch file does run either after I type its name at the command line in the window, or if, instead, from the Start Menu I use Run and in the "Open:" input box type:

  cmd /c path_to_bat_file\batch_filename.bat

How can I reassociate batch files with the default Window API action?

I tried the standard approacyh of going to Tools > Folder Options File Types and associating .bat files with type MS-DOS Batch File and specifying that .bat files should be opened with Windows Command Processor.  But that does not correct the problem.

I also checked the Registry.  In HKEY_CLASSES_ROOT, the entry for .bat gives under key PersistentHandler a CLSID that has under its own key PersistentAddinsRequired a subkey that points to a CLSID whose subkey InProcServer has two subkeys:  (Default) with value query.dll and ThreadingModel with value Both.

Note that this behavior appeared after I installed JP Software's 4NT command processor and opted to make it the default processor for command prompt windows.  However, I have since uninstalled 4NT.

Some additional information:   I re-installed 4NT, but still, clicking a .bat file's icon (or shortcut to
the same) does NOT run it -- it just opens a 4NT command window.

Currently, with 4NT re-installed, the same PersistentHandler chain of
references in the Registry persists. Currently, the value in HKLM for
batfile > shell > open > command is:

"D:\Utilities\JPSoft\4NT7\4nt.exe" /c "%1" %*

This really has me puzzled.  The /c part of the registry key is, I thought, what makes the command processor run the command that follows it.

Hi Murrayhome,

The default .BAT file association fix is available here.

Unfortunately restoring the default .BAT file association like that (even after un-installing 4NT again, and rebooting) does NOT fix the problem.  Still when I double-click a .bat file, all that happens is that a command prompt window opens up with the command prompt showing the path to the .bat file I tried to run.  But the .bat file has NOT run!

Can you post the .BAT file association info. The "FileExtInfo" utility can gather all the info to a file.
