Did you look at the value returned by the library function `system'?
I bet it's -1, which means your pathname is incorrect (i.e. the named
program does not exist).  That's hardly ``nothing happens'' ;-)

Or maybe you forgot to double some backslash.

Anyway, I just tried the simple program attached below (after
replacing the program's pathname with something that is correct for my
system), and it did work.

One more evidence that some backslash somewhere was forgotten.

#include <stdlib.h>

char *call = "\"c:\\program files\\javasoft\\jre\\1.1\\bin\\jre.exe\"";

int main (void)
{
  return system (call);
}
