title: Passing constants as arguments in INNO's Exec()
body: <p>I have created an installer using Inno Setup in which I am executing an exe that I created to create a small service inside Windows XP. I need to pass two arguments to the exe - "-install" and the path of the installation directory. I have no way of expanding the constant {app} to pass the actual value inside of {app}. Is there some way of doing this? </p>
  
  <p>Thanks</p>
