Standalone path

Hi, how can i get the path of a standalone inside the patch?
In a patch, before build, i use [thispatcher] with the "path" message and it does return the patch path. But when i make it into a standalone it returns a backslash. why is that? the patch works perfect, but when built, it does not!
I work on windows.
is there any other way of getting the path in a standalone or a way ti "fix" the thispatcher?
Thank you all,
Nickolas
