I'm glad it works for you, but your lnked also mentioned "It fiddler is also available as portable tool, then browser hooks may not work, rest is fine."
This sounds exactly like my own experience and I've tried it in multiple computers.
I've previously mentioned having to delete a registry key.
I highly recommend everyone who act upon this topic, to follow the linked Stackoverflow question because I have comments there about other needed steps too, not just removing the registry key.
The only thing missing is the hooks...
