Hi I want to silent install avast 2014.9.0.2007

I used the “/VERYSILENT /NORESTART /SP-” parameters but this is not success.

What is the problem?

I’m not sure, but I suspect that the command line parameters have been changed on avast v9.
Hope some of the developers could help.
Which is the operational system on which you’re trying to install it?
