Please try updating to RC-1a (released just about half an hour ago). Hopefully it will solve the problem.
Also, I’ve uploaded a self-extracting package (interactive setup wizard) of the latest avast managed version installation: http://www2.asw.cz/misc/setup_av_net.exe . You can use it to deploy the product to your machines even if the AMS is offline (and the InstPkgs folder has not yet been generated) - which I hope won’t be the case anymore… 
Please run it with either /client or /server command line argument (depending on whether installing the Server Edition or the regular (workstation) one).
Thanks
