How to load/register pro version on new computer?

Avast Free Antivirus / Premium Security
1

Hi,
I recently moved to a new computer and I’d like to move my 3 year pro version to the new computer. I have not been successful being able to load the software and enter my license key - do I load up the trial of the Pro version and then enter the license key - Where?

Thanks for any guidance!

I suggest an installation from the scratch:

  1. Uninstall avast from Control Panel first.
  2. Boot.
  3. Use Avast Uninstall for complete uninstallation.
  4. Boot.
  5. Install again the last version.
  6. Boot.
  7. Check and post the results.

To insert the Pro key, see the tutorial: http://www.avast.com/files/tutorials/insert_key.htm
