"Early" PLabs installers stuffed python23.dll into the system directory, and
scribbled registry entries under HKLM.  They may also try to update a couple
MSVC runtime DLLs in the system directory (e.g., Win95 didn't come with
msvcrt.dll out of the box, and Python needs it).

"Later" PLabs installers (sometime shortly after I started building them)
grew a choice, controlled by a radio button for doing an Admin or non-Admin
install.  The Admin install is the default if the user running the installer
has admin privileges, and acts like early PLabs installers.  The non-Admin
install is the default if the user running the installer does not have admin
privileges, writes nothing to a system directory, scribbles registry entries
under HKCU, and installs python23.dll and a couple MSVC runtime DLLs into
the root Python directory.

I don't think Thomas has changed any of that (yet <wink>).
