Hi I installed 2 new Avast Free Editions on Customer Notebooks.

Possible. Any Suggestions?

That is the Problem. Avast was installed on a Fresh new installed Windows 7.
Normaly after its installation AVAST Pops up and want to register.
Now Avast pops up and provide only an Upgrade. I miss the green
Register Button.

If you experience any issues with on-line registration, use the off-line registration.
