Do you have a workaround for those of using SOA Console?
As noted above, this was an issue within 8.0.1606.
Kind Regards, Stephen
Update: As an experiment, I have manually edited "C:\ProgramData\AVAST Software\Avast\avast5.ini" on a couple of workstations (setting "wscregistered_v6=0"), and this seems to supress the error. It is quicker than a manual re-install, but still requires me to visit each client.
