I tried to install LinkSnooper on my Windows 7 computer, as described in the documentation and here. According to the answer of @Todd Gayley, I entered the following string in the field MLOpen:

"-LinkMode Launch -LinkName '\""<>
FileNameJoin[{$InstallationDirectory,"SystemFiles", "Java", "Windows-x86-64", "bin", "javaw.exe"}]<>
"\" -classpath \""<>
FileNameJoin[{$InstallationDirectory,"SystemFiles","Links","JLink","JLink.jar"}]<>
"\" com.wolfram.jlink.util.LinkSnooper -kernelname \""<>
FileNameJoin[{$InstallationDirectory,"mathkernel.exe"}]<>
"\"'"

(* -LinkMode Launch -LinkName '"C:\Program Files\Wolfram Research\Mathematica\10.0\SystemFiles\Java\Windows-x86-64\bin\javaw.exe" -classpath "C:\Program Files\Wolfram Research\Mathematica\10.0\SystemFiles\Links\JLink\JLink.jar" com.wolfram.jlink.util.LinkSnooper -kernelname "C:\Program Files\Wolfram Research\Mathematica\10.0\mathkernel.exe"' *)

When I start the kernel, just as in the question, a file system browser asks me for a MathLink program. The same happens when I replace -classpath with -cp.

I also read the solution of @halirutan given here for a related problem, but I could not find a variant of that method for only starting up LinkSnooper.

I would highly appreciate if someone could point me to what I did wrong.

What is the simplest way to set up LinkSnooper to monitor the communication between the Kernel and the Front End?

I am looking for an answer that works on all platforms, including 32-bit Windows.
