Question

我正在创建PowerShell脚本，以便通过创建新组件，功能和属性从MSI生成MST。在创建组件时，我遇到了一个问题。以下是我的代码段和错误消息。

代码：

$windowsInstaller = New-Object -ComObject WindowsInstaller.Installer             
$database1 = $windowsInstaller.GetType().InvokeMember(
    "OpenDatabase", 
    "InvokeMethod", 
    $Null, 
    $windowsInstaller, 
    @($database1Path, $msiOpenDatabaseModeReadOnly)
)  


#open 'backup' MSI in transact mode
$database2 = $windowsInstaller.GetType().InvokeMember(
    "OpenDatabase", 
    "InvokeMethod", 
    $Null, 
    $windowsInstaller, 
    @($database2Path, $msiOpenDatabaseModeTransact)
) 

$query2 = "INSERT INTO ``Component`` (``Component``,``ComponentId``,``Directory_``,``Attributes``,``Condition``,``KeyPath``,``Full Directory``) VALUES ('My_Branding','{B960EF8B-A4AC-447C-91F3-C19CCAC3899E}','INSTALLDIR','4',' ',' ','Windows\System32\Macromed\Flash')"
$View2 = $database2.GetType().InvokeMember("OpenView","InvokeMethod",$Null,$database2,($query2))
$View2.GetType().InvokeMember("Execute", "InvokeMethod", $Null, $View2, $Null)      
$View2.GetType().InvokeMember("Close", "InvokeMethod", $Null, $View2, $Null)
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($View2) | Out-Null

#Commit the changes to our backup database
$database2.GetType().InvokeMember("Commit", "InvokeMethod", $Null, $database2, $Null)


#Generate a transform (the difference between our original MSI and our Backup MSI)  
$transformSuccess = $database2.GetType().InvokeMember(
    "GenerateTransform", 
    "InvokeMethod", 
    $Null, 
    $database2, 
    @($database1,$MSTPath)
)  

#Create a Summary Information Stream for the MST
$transformSummarySuccess = $database2.GetType().InvokeMember(
    "CreateTransformSummaryInfo", 
    "InvokeMethod", 
    $Null, 
    $database2, 
    @($database1,$MSTPath, $msiTransformErrorNone, $msiTransformValidationNone)
) 



#Release objects from memory
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($database1) | Out-Null 
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($database2) | Out-Null
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($windowsInstaller) | Out-Null
