I'm attempting to include an install of SQL Server 2008 Express w/Adv. Services with an installation package, but am having a heck of a time getting the installation to complete.

Typically, this installation will take place on brand-new servers that get shipped to new customers, but this won't always be the case: Sometimes, the installation will take place on machines already in use, and so I've been told the installer has to work for XP x86 and x64 and Win 7 x32 and x64.

The command line I'm passing in is: setup.exe /ACTION=INSTALL /INSTANCENAME="MSSQLSERVER" /HIDECONSOLE /QS /FEATURES="SQLENGINE" "REPLICATION" "FULLTEXT" "RS" "BIDS" "SSMS" "SNAC_SDK" "OCS" /SECURITYMODE=SQL /SAPWD="aStrongPassword" /NPENABLED=1 /TCPENABLED=1 /SQLSYSADMINACCOUNTS="%USERDOMAIN%\Administrator" SQLSVCACCOUNT="NT AUTHORITY\Network Service"

(This is only my most recent attempt, in which I used a SQLSYSADMINACCOUNTS value that I saw in a posting elsewhere on this site. I've tried lots of combinations from various sites.)

The SQL installer's Summary.txt begins:

Exit code (Decimal): -2068578304 Exit facility code: 1204 Exit error code: 0 Exit message: The specified credentials that were provided for the SQL Server service are not valid. To continue, provide a valid account and password for the SQL Server service.

This seems simple enough to fix (and maybe I"m overlooking something obvious), which is why it's driving me nuts.

If any of you have any suggestions, I'd appreciate it. (I've got to take off for the weekend, so don't interpret my delayed response as a lack of interest.)

Thanks.
