Thanks. Yes, the installer is not patient enough for sure but I am
afraid there is also another issue there since sometimes the services
does not start.
Regarding the, crash one peculiar thing in the screenshot is that the
instruction is said to be at address zero not just the memory it is
accessing, I never actually seen that kind of message before (i.e. with
two zeros).
