I know the wiki and already understood your first (and only) statement. But unsupported OS or not - something is wrong with RC1 and THAT is just reality - accept it or ignore it!
i close this thread now, because its going from technical to personal.
as we clearly state in the wiki, we do not support certain OperatingSystems, simply because Microsoft does not support them in the way we would need it.
means that the do not release required patches.
if it works, good then you are lucky.
if not, than we can not change that.
