error with license key (internet security)

Whenever i try to enter the license key for internet security, it shows an area as shown in the photo. What is the problem? I have tried reinstalling but the same error occur.

Use the license file, not the activation code.

how do i get the license file?

https://www.avast.com/resend-license-paid.php

Now after i downloaded the activation file, it says this.

Hi,

A clean re-install should solve this problem. Use http://files.avast.com/iavs9x/avastclear.exe to uninstall Avast and then download and install the latest build from http://files.avast.com/iavs9x/avast_internet_security_setup.exe

PD: Did you ever install Kaspersky?

This error pop-up when i try to install from the full installer. Previously it was like this too.

Nope, i just reformated the laptop. the previous antivirus was eset nod32

Hi,

Could you please send us a support package http://utils.support.tools.avast.com/tools/support/utils/avastsupport.exe
Please post the ID here to locate it.

If I understand correctly, you had Nod32, reinstalled Windows and then installed Avast? There should be no Nod32 files remaining, right?

What do you want me to do? Anyway i submitted a report.

Nope, after i reformated everything, i had eset nod32. I uninstalled it. Now im trying to use avast and it doesnt work.

You need to use the uninstall tool from E-Set and not just remove through control panel.
If you haven’t used it:

  • Remove E-Set and avast through control panel
  • Reboot
  • Run the uninstall tools for both
  • Reboot
  • Install avast

both antivirus are not in the control panel.

As Eddy has said, run the removal tools for Avast and Eset before attempting to re-install Avast.
