We have an InstallShield installation that installs SQL Server 2005 Express
as a prerequiste to our software (that means that it is installed before our
setup wizard launchs). Normally this works fine but some customers experience
this error. During the installation of SQL Server, the following error
message pops up when the component "SQL Server Databaser Services" has status
"Configuring"component .

"SQL Server Setup could not validate the service accounts. Either the
service accounts have not been provided for all of the services being
installed, or the specified username or password is incorrect. For each
service, specify a valid username, password, and domain, or specify a
built-in system account"

The error number is 28075 in the summary.txt and the detailed MSI log.

After searching the forums etc. I found the following forum post:

It appears that the localized account is the cause of the problem in my case
also.

The command InstallShield pass to the sqlexpr.exe (sql server 2005 express
service pack 2) is:
/qb INSTANCENAME=PRODACAPO SAPWD=******* SECURITYMODE=SQL
DISABLENETWORKPROTOCOLS=0 ADDLOCAL=ALL SQLACCOUNT="NT AUTHORITY\SYSTEM"

question is if it's possible to pass a well-known-sid instead of a name of
the account NT_AUTHORITY\SYSTEM, since that is called "NT INSTANS\LOKAL
TJÄNST" if run on a Swedish XP/Vista install, or am I forced to determine the
localized account name and pass that to the sqlexpr.exe instead.
