free registration number

A couple of days ago, I requested a registration number for the free version but I haven’t received it yet. Is this a normal delay?

I requested a reg. no a few months ago using the same email address. Would this produce a problem for the system?

Thanks for the help

Avast 5.x and Avast 6.x Free versions can be registered directly from the AvastUI. No need to wait for an email.

I tried registering from the Avast UI but it did not work.

Do an Avast Repair

For a repair of avast. Windows, Add Remove programs, select ‘avast! Anti-Virus,’ click the Change/Remove button from the pop-up window, scroll down to Repair, click next and follow.

And try again registering from the Avast UI
