I have the same issues.
I am TRYING to get a refund from digital river, but they are referring me to avast for technical help.
I don't WANT or NEED any so called "Technical Help" it just doesn't perform as promised and I don't need anyone to show me how it MIGHT BE useful in ways that don't interest me, e.g. for 32 bit systems.
IF/WHEN it becomes useful on 64 bit systems I might pursue the problem of the very stale virus data file and the inability to connect to the web for a current file, i.e. the lack of ethernet and wireless drivers, but those issues are so far off that I would prefer a refund - then I can decide whether or not to purchase some other version later.
I can't even get a current .vps file using a running system, the installed and running version of avast seems to use only .vpx , which the rescue disk can't/won't use.
Frustrating at best !!!
