Here’s a small chunk of code from a recent request asking how to stream a file into the binary table of a Windows Installer using Powershell:

$msiOpenDatabaseModeReadOnly = 0
$msiOpenDatabaseModeTransact = 1
$windowsInstaller = New-Object -ComObject windowsInstaller.Installer
$pathToMSI = "C:\Users\xxxx\Desktop\AlkaneExample.msi"
$database2 = $windowsInstaller.GetType().InvokeMember("OpenDatabase", "InvokeMethod", $null, $windowsInstaller, @($pathToMSI, $msiOpenDatabaseModeTransact))
$query = "INSERT INTO `Binary` (`Name`,`Data`) Values(?,?)"
$View = $database2.GetType().InvokeMember("OpenView","InvokeMethod",$Null,$database2,($query))
$binaryrecord = $windowsInstaller.GetType().InvokeMember("CreateRecord", "InvokeMethod", $null, $windowsInstaller, 2)  
$binaryrecord.GetType().InvokeMember("StringData", "SetProperty", $null, $binaryrecord, @(1, "AlkaneBinary"))
$fileToStream = "C:\Alkane\AlkaneFile.txt"
$binaryrecord.GetType().InvokeMember("SetStream","InvokeMethod", $null, $binaryrecord, @(2, $fileToStream))
$View.GetType().InvokeMember("Execute", "InvokeMethod", $Null, $View, $binaryrecord)
$database2.GetType().InvokeMember("Commit", "InvokeMethod", $null, $database2, $null)
$View.GetType().InvokeMember("Close", "InvokeMethod", $Null, $View, $Null)
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($View) | Out-Null
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($binaryrecord) | Out-Null
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($database2) | Out-Null
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($windowsInstaller) | Out-Null

  1. Thanks Kae!!

    It worked perfectly! Just a note for anyone else trying to add a custom action with binary data i.e. VB script, remember to match the name column “AlkaneBinary” in the binary table with the Source column in the custom action table.

    Thanks again.

  2. When i try to run the code below, it fails. What am i doing wrong?

    $msiOpenDatabaseModeReadOnly = 0
    $msiOpenDatabaseModeTransact = 1

    $windowsInstaller = New-Object -ComObject windowsInstaller.Installer

    $pathToMSI = “C:\Temp\Test.msi”

    $database = $windowsInstaller.GetType().InvokeMember(“OpenDatabase”, “InvokeMethod”, $null, $windowsInstaller, @($pathToMSI, $msiOpenDatabaseModeTransact))

    $query = “INSERT INTO `Binary` (`Name`,`Data`) Values(?,?)”
    $View = $database.GetType().InvokeMember(“OpenView”, “InvokeMethod”, $Null, $database, ($query))

    $binaryrecord = $windowsInstaller.GetType().InvokeMember(“CreateRecord”, “InvokeMethod”, $null, $windowsInstaller, 2)

    $binaryrecord.GetType().InvokeMember(“StringData”, “SetProperty”, $null, $binaryrecord, @(1, “Test”))

    $fileToStream = “C:\Temp\test.txt”

    $binaryrecord.GetType().InvokeMember(“SetStream”, “InvokeMethod”, $null, $binaryrecord, @(2, $fileToStream))

    $View.GetType().InvokeMember(“Execute”, “InvokeMethod”, $Null, $View, $binaryrecord)

    $View.GetType().InvokeMember(“Close”, “InvokeMethod”, $Null, $View, $Null)

    [System.Runtime.Interopservices.Marshal]::ReleaseComObject($View) | Out-Null
