I have the same problem here. It seems that something is going wrong in config file reading.
The notepad.exe entry specified in documentation/samples/config doesn't work too.
Well, if my wetware HTML parser is working today, I think I understand your problem. Just rename regedit.exe to "winregedit.exe" (or whatever you like), or create a symlink or copy of the native version. (some configs don't respect symlinks).
