My avast installation is never successful

Hello all,
I used to use avast premier and never have a problem, I stop using it for a while and picked it up again recently. Now the installation always fail. I am trying to install avast premier on my win 10 64 bit. There are always these issues:

  1. During the first part of the installation. It is always downloading “vps_win32-52.vpx” and never proceed any further
  2. If I can get pass the first stage, and the main client of avast installation just stuck at 16% and never proceed any further, if I restart my pc it is still 16%. Delete avast and reinstall, still stuck at 16% percent.
    I tried reseting my pc, install nothing else except avast. Still stuck at 16%. I even tried to delete my raid0 set up and performed a total clean install, and guess what, stuck at 16% percent. I am losing my patient and just want to smash something so bad

Try a clean install.

Are you using the full off-line installation file (241MB) or the on-line stub installer much, much smaller (6MB).

See https://forum.avast.com/index.php?topic=210678.0 for a full list of off-line installation files.
