Can't get debug mode to work

I'm trying to run in debug mode but something's not working right. I read the instructions on the documentation page and as far as I know, I'm following them to the letter.

In the Run box I entered: "C:\Program Files\Defraggler\Defraggler.exe/debug" without quotes and pressed OK. It gives this error: Windows cannot find 'C:\Program.' Make sure you typed the name correctly, and then try again. If I run the same command without /debug at the end it works okay. It does the same thing in XP and Vista. What am I missing here?

Scratch that. Found the answer in another thread entitled: "5 tb raid fails and can't debug." (Thanks Richard S.)

In the Run box I entered: "C:\Program Files\Defraggler\Defraggler.exe/debug" without quotes and pressed OK.

Although you stated scratch that, the command line isn't correct.

This is the command line with quotes, note that there's a space that separates /debug from the defraggler.exe:

"C:\Program Files\Defraggler\Defraggler.exe" /debug
