Thanks for the prompt response but I think I may have figured it out. Reading the note, that when typing commands in the "cmd.exe" shell, you should use double quotes instead of single quotes as shown in some examples, from http://www.sno.phy.queensu.ca/~phil/exiftool/ I wrapped by original line double quotes. I switched to single quotes and I got the same output as if I have just exiftool'ed the file. I'm assuming that this is the succeed output.

So what happened? Well I'm on Windows Vista but I'm working in PowerShell where the rules are reversed from a normal cmd.exe shell.
