There is a very long thread on

that I have not deleted in case the problem should show up again. The
solution mentioned there is to just delete .emacs.d/server as Juanma
suggested here.

I do not remember the details now, but I think it is related to
privilege escalation in the sub process started from the installer. It
seems that this is working differently on Windows versions after XP. I
am running XP myself so I do not know that very much about it. If
anyone wants to step in and fix this problem with the installer (which
uses Inno Setup) I would be glad.
