Are you asking how to install the license for the Internet Security (AIS) after reinstalling it?

Once you have purchased Avast Internet Security 5.0, you will receive an email with your license file attached to the email address specified during the purchase process. You need to have Avast Internet Security 5.0 already installed on your machine to insert the license file into the program according these instructions:

Please let us know if you have any additional questions. Thank you.

I didn’t know that there was a life time license ???

Where did you get the lifetime license?

First thanks for the replies.
I have no license for life, is the automatic translation from Spanish to English.
I have a license for 1 year, until two days ago it worked fine.
I had to uninstall Avast Internet Security 5.0, in just a PC.
The other two pcs, it works correctly.
In the pc uninstalled it when I installed it again and I turned to insert the file is when I do not recognize the file as good and does not work on 5.0

Thanks

I suggest an installation from scratch because our latest version is 5.1(5.1.889):

  1. Download the latest version of avast! Uninstall Utility and save it.
  2. Download the latest avast! version and save it.
  3. Uninstall avast from Control Panel (if possible). If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after that.
  4. Run the avast! Uninstall Utility saved on 1. If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after you’ve run it.
  5. Install avast! using the setup saved on 2. Boot.
  6. Register your free copy or add the license key for Pro.
  7. Check and post the results. If, for any reason, you did not solve, try doing the step 3 in Safe Mode anyway.

Thank you very much Swarnava
I followed the 7 steps and it works for me perfectly.
Step 3 has not been done so in safe mode.

Thanks :slight_smile: :slight_smile:
