To nit-pick, it's metadata, not microdata. No DAZ installer that I am aware of has hard coded paths pointing to anything. The older versions don't show a path (well, unless you let them search out your copy of poser.exe, should you have one) - they start at the root, or possibly in the folder you run them from. The last few generations have stored the last used path (and latterly, the last used Poser and DS paths) in the dzinstall.ini file - and the location in which that is stored has changed a couple of times, which may make installers of different vintages inconsistent in the path they offer.
