I just ran into the same problem and I think there is a change to skip this by simply editing a file called "launcher.cfg". There's a line "RUN = . register.dat", and similar which is ignored by the # mark and contains "RUN = Game to be started blaa blaa" (forgot what it said). I tried ignoring the registering process and tried few lines on the "RUN =" like "Dune2000", "Dune2k", "Dune", none of them didn't seem to work, "Dune2000" tried to execute the dune2000.exe quitea few times, so at least it did something. So if we're lucky, we only need a working argument for that line, so help us anyone who has the game already installed and working. Posting the whole contents of the launcher file would be very nice.
