ok i downloaded the manual download and it installed.
but-
i am still unable to register.
the current version date is now 130814-01
and auto update seems to be downloading.

a repair dialog just opened and asked me if i wanted to repair avast.
i clicked yes.
a dialog message just opened that reads:
"avast!4 is probably not yet installed or installation is broken.
download full install package and reinstall.
