Yes, dumper.exe works.

You might want to check whether dumper returns with exit status 0 - it's 
not all that chatty.

== SNIP ==
try something like this in your dumper.bat:
dumper.exe -d %1 %2 %3
if errorlevel 1 goto had_err
if errorlevel 0 goto endlast

:had_err
echo %errorlevel%
echo error!

:endlast
pause

== SNAP ==

If you get an errorlevel other than 0, it will say there's an error and 
give you the return code. If the dumper os not sane, that code will be 
65535; if there's n error on the command line, it will be 1.
That won't tell you why the dumper isn't sane, but it will at least get 
you somewhere.

Have fun!
