Possible solution for WinXP "UI failed to load"

Please see the topic “Avast Premier full version 18.3.2333 installer needed!” for the results of my layman research. Maybe it works for other Avast products besides Premier. Unfortunately the sample size of my research is only one XP PC. :slight_smile:
