I think PJ was referring to the fact that you cannot edit the registry (regedt32.exe) unless you have administrative rights on the machine, which is correct. Most default XP installs allow the first user account full administrative rights. The funny thing is, OSX just installs Poser (*nix has no 'registry' - IMHO a good thing), and since its libraries are local, you don't need sudo/root (the password-entering blurb you see) to install it there. (OSX has a whole different security model, which works very well). /P
