We have a system in which there a SQL Server Express 2008 default instance called "SQLExpress".
Normally the SQL Server Express default instance is called "MSSQLSERVER".
Now we have an application installer with a SQL Server Express 2008 prerequisite.
This prerequisite tries to install a named instance called "SQLExpress".
This fails with the message:
Process exited with code -2068578304
The commandline arguments used by the installer are:
/q /hideconsole /action=Install /features=SQL /instancename=SQLEXPRESS /enableranu=1 /sqlsvcaccount="NT Authority\Network Service" /AddCurrentUserAsSqlAdmin /skiprules=RebootRequiredCheck
How can we handle this case?
