What do you mean with target dir? I guess the question goes into the 
direction of an already existing directory?

If not already there, add to your root component should an 
installscript.qs. Inside there, specify a constructor like this:

// constructor
function Component()
{
     var programFiles = installer.environmentVariable("ProgramFiles");
     if (programFiles != "")
         installer.setValue("TargetDir", programFiles + "/foo");
}

I've tried this here and it sets the "TargetDir" variable to either 
"C:\Program Files" or "C:\Program Files (x86)". Please note that by 
default spaces are not allowed inside the target path, you can overwrite 
the behavior by setting <AllowSpaceInPath>true</AllowSpaceInPath> in 
your config.xml. See also:
