LEGO Mindstorms RCX 2.0

Still have LEGO Mindstorms RCX 2.0 from ca. 2003. The original software that came with it does not run under Vista. It does run under Windows XP, but caused 2 problems:

1. Will quit with an out-of-memory error when a current version of Quicktime is installed. Installing the older version of QT from the LEGO CD works, but will break online movie sites that require a more recent QT.
2. The "Robotics Invention System" software will auto-start when Windows starts up. Remove the corresponding entry from the registry via regedit.exe in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

LEJOS, http://lejos.sourceforge.net, might be a better choice for the actual program, but the graphical LEGO program is neat for children.
