Convert from Avast 5 Internet Security to Avast 5 Free

Avast Free Antivirus / Premium Security
1

I would like to convert from Avast 5 Internet Security to Avast 5 Free Edition.

There are three blocks available when I click insert license, however; the registration code for the free edition is a longer code than the space provided.
How can I convert?

I would suggest an installation from scratch:

  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.
