i am not sure then. the only people who have said they were getting
the 2869 error were all running the .msi directly. once they ran the
.exe, it installed properly.
the only other thing i can suggest is to make sure you are running as
an administrator when you try the install. you dont have to be an
admin to run GfW, but you probably do to install it (since it writes
to Program Files and the registry upon installation).
