The following script will execute a command with the .run method, but fail executing the exact same string using .exec:

Option Explicit
Main

Sub Main
Dim WshShell, Proc, strCmd
Set WshShell = WScript.CreateObject("WScript.Shell")
   strCmd = """C:\Program Files\Exiftool\exiftool.pl"" -common "
   strCmd = strCmd & """C:\Downloads\Capture_00001.JPG"""
   WshShell.Run strCmd, true
   Proc = WshShell.exec(strCmd)
End Sub

Error message is
Error:      "C:\Program Files\Exiftool\exiftool.pl" -common "C:\Downloads\Capture_00001.JPG" is not a valid Win32 application.
Source:   WshShell.Exec

The command simply outputs EXIF info, by the way. Any ideas why the .exec method won't work when .run accepts the command just fine??

My first guess would be an issue with file associations. For some reason the .Exec method may not be seeing the association for perl files. Try changing your command to call perl.exe with the full path.

You are right. I happened to run across the solution myself not too long after I posted :-| But I guess it doesn't hurt to have it here as well.

It appears that the .run method can resolve some file dependencies whereas the .exec method will only accept Win/DOS executables. So exiftool.pl needs to go as an argument to the actual executable which is Perl. I had another error as wel; forgot "set" in front of the WshShell.exec line. Changed the code to the following and it worked:

   strCmd = "perl ""C:\Program Files\Exiftool\exiftool.pl"" -common "
   strCmd = strCmd & """C:\Downloads\Capture_00001.JPG"""
   set Proc = WshShell.exec(strCmd)

Thanks ebgreen!
