Subject: When am trying to Insert Activation Key Avast Cleanup it says “The number of successful activations hs reached the limit.” and when I try to activate its also not happening. I had create Ticket ID: 127144 last 11 days, still there is no reply. Which kind of support avast giving its seems very clearly. And there is no support contact no for India. Really its very harassing.
There sure is “support contact” for India and you already found it.
It is called the ticket system 
Due to the recent holidays avast has fallen a bit behind with handling the tickets.
Just have patience please.
but its already 11 days gone.
You need to count in business days as has been explained many times.
But please post your ticket number here.
Ticket ID: 127144
Reported to Moroni, wait for his reply.
Hi,
The activation of Avast Cleanup is limited to the number of computers allowed by the license.
Your license has reached the maximum activations allowed as it was activated in more systems than it was valid for.
I’ve reset it so you can use it again. Please be sure not to activate it on more than one computer.

Respected Sir,
I had not tried to activate in other system. Actually the fact is i had made clean installations of OS in my lappy for many times and when i tried to activate it shows that error of activation. And I know that I had purchase the license for one computer so never tried to activate more than one pc. Anyways thanks for your kind support. Thanks a lot. Now am very happy. Thank you so much.
