Hello,
I am having trouble installing sql express from a command line on an XP o/s other than English, I know French and German have the problem I suspect this is caused by setting the sql account to ="NT AUTHORITY\SYSTEM" my guess is that this is a localized string.
I get the following error
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.
This is my command line
setup.exe" /QB REBOOT=REALLYSUPPRESS ADDLOCAL=ALL SQLBROWSERACCOUNT="NT AUTHORITY\SYSTEM" SQLBROWSERPASSWORD= SQLACCOUNT="NT AUTHORITY\SYSTEM" SQLPASSWORD= AGTACCOUNT="NT AUTHORITY\SYSTEM" AGTACCOUNT= SECURITYMODE=SQL INSTANCENAME=KBMSS SAPWD=kbmsa DISABLENETWORKPROTOCOLS=0 SQLAUTOSTART=1 SCCCHECKLEVEL=IncompatibleComponents:1 ERRORREPORTING=2
Anyone else run into this
Thanks,
Michael Gustafson

I found the answer to the problem here, the service names are localized.
