Just bought Avast Internet security premium for 1 year and can´t activate it

What should I do?

How are you trying to activate it ?
What exact version of avast ?
If you are getting a error, what is the exact error ?
Is there any other security (related) software installed ? (or was there)

Hi Eddy, I received an email with instructions and clicked the link to download it. It starts downloading it but then it stops and does not give me a chance to follow the rest of the instructions, no error displays.
How am I supposed to find the versión? I have the order number 20934160162.
No other security software installed other than Avast. I´m renewing my subscription that just ended 2 days ago.

Download the license file through your avast account and use that. > https://my.avast.com

Just did as you said but I get an error response that says that the licence is not valid or currupted.

Perform a clean installation of the latest IS version and try again.

Problem was solved after uninstalling the previous Avast antivirus, restarting a few times and then it finally allowed the instalation of the new versión.
Thansk for the help Eddy.

You’re welcome.
