Its fixed now!
For me the solution was to stop everything that was already running (including antivirus, firewalls - all that stuff in the bottom right corner of your screen). I suppose that the "bottom-right-corner" stuff is implemented as "services" in XP, and these items must somehow get in the way of the installer when it tries to start the SQL service. Anyway, its fixed now! Hope this helps the rest who have (and will in the future) come up against this problem.
PS: I did not have the problem on my old win 98 system (which does not do "services"), and so the installation was able to complete without this issue arising.
