Hi,

please do two things:

  1. Send me your setup.log and setup.ini files from avast4\setup directory together with short explanation (link here or cut’n’paste of your message) to setup-support AT asw DOT cz

  2. Easiest way to fix it fast would be to download whole ‘setupeng.exe’ and trying to update from it or uninstall/install cycle.

thanks,
