Free Avast Software problem

Avast Free Antivirus / Premium Security
1

I’ve been using the free Avast software for a few months with no problem, til now. When I click on the icon to bring up Avast to do a system scan, Avast does not open, but a box pops up saying…failed to load language dll (1909\UlLangRes.dll)
What do I do to get this thing going again? Any help will be appreciated. Thanks.

If it fails, I 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.
