我尝试使用PowerShell自动安装SQL Server Express 2012，如以下脚本所示：
$Password = "MyP@ssw0rd"
$instanceName = "SQLEXPRESS"
$InstanceId = "SQLEXPRESS"
$User = "sqlsvr12ex"
$SQLAdmins = "VLILEN014120VM\Administrator"
$securestring = ConvertTo-SecureString $Password -AsPlainText -Force
$cmd = @"
"C:\SQLK\SQLEXPR_x64_ENU.exe" /QS /IACCEPTSQLSERVERLICENSETERMS /ACTION=install /FEATURES=SQLENGINE
/INSTANCENAME=$($instanceName) /INSTANCEID=$($InstanceId) /SQLSVCACCOUNT="$($User)" /SQLSVCPASSW0RD=""$($securestring)"
/SQLSYSADMINACCOUNTS="$($SQLAdmins)" /INDICATEPROGRESS
"@
Write-Host "Installing"
Write-Host $cmd
& cmd.exe /c $cmd
但是，我无法安装它并收到以下错误消息：
