postgres silent install bug?

Hello everyone,

I am trying to run a silent install of Postgres 8.3 using the following command line:

MSIEXEC /i "postgresql-8.3-int.msi" /qb /log "c:\mydir\logfile.txt" ADDLOCAL="server,nls,psql,pgadmin,includefiles,libfiles,binfiles" INTERNALLAUNCH=1 DOSERVICE=1 CREATESERVICEUSER=0 DOINITDB=1 SERVICEDOMAIN="<ComputerName>" SERVICEACCOUNT="postgres" SERVICEPASSWORD="randompass1" SERVICENAME="PostgreSQL Database Server 8.3" SUPERUSER="postgres" SUPERPASSWORD="yaright" LOCALE=C ENCODING=SQL_ASCII LISTENPORT=5432 PERMITREMOTE=1 PL_PGSQL=1 PL_PERL=1 PL_PERLU=1 PL_TCL=0 PL_TCLU=0 PL_PYTHONU=0 BASEDIR="c:\mydir\PostgreSQL\8.3"

I get the following error shortly after I see the install window start and a small amount of progress: "User account ¡¡¡¡¡¡¡s¡¡¡¡\¡¡¡¡¡W does not exist"

Has anyone encountered this with the postgresql-8.3-int.msi file and how can I get around it?

Many thanks,
Mike
