Error 421 => “The account name is invalid or does not exist, or the password is invalid for the account name specified.”

but why other services are installing?

4

can you answer? why other services are installed except avast! Antivirus?

This is because all other services run under the LocalSystem account, and not the account specified in the installation package.

And, as a matter of fact, I’d recommend installing the “avast! Antivirus” service under the LocalSystem account as well. This is done by simply leaving the username and password fields blank. The truth is, the latest version of the netclient installer doesn’t ask for this info anymore and always uses the LocalSystem account (AFAIK).
