because i don't need to be always nice, lets be bit harsh
what i don't get why Avast can't have installer which needs only
1. know where Avast files are installed
2. know there are already existing config / setting files
then all it needs to do is
3. contact some servers to obtain latest build servers mirrors (some central forwarder on mirrors.avast.com)
4. download the files
5. overwrite everything with LAST build
6. utilize existing config / settings file, backup them, recreate new importing existing values
7. start freshly updated version
8. profit
from my point of view : 3 years passed, Avast has still same POS updater ... (using registry for builds lol^lol*lol)
note: resolved the cause by myself (headbanging over table, cursing coding and such to lost track on what all i tried to force the updater work as it should)
status: 1401 > 1407 ... it works
