I am trying to use this code from the tutorial Getting version from MSI without installing it, but when I try to add the "msi.dll" to Visual Studio 2010 as a reference I get this error.
Could not load file or assembly 'msi.dll' or one of its dependencies. The module was expected to contain an assembly manifest.
This file may not be a managed assembly
Use "Microsoft.Deployment.WindowsInstaller.dll" from the Wix project's Deployment Tools Foundation (DTF). DTF provides a managed wrapper for much of msi.dll. Wix also provides helpful documentation.
Using DTF here is how I accessed the version number of an msi in C#
using Microsoft.Deployment.WindowsInstaller;
namespace Msi.Tables
{
public class PropertyTable
{
public static string Get(string msi, string name)
{
using (Database db = new Database(msi))
{
return db.ExecuteScalar("SELECT `Value` FROM `Property` WHERE `Property` = '{0}'", name) as string;
}
}
public static void Set(string msi, string name, string value)
{
using (Database db = new Database(msi, DatabaseOpenMode.Direct))
{
db.Execute("UPDATE `Property` SET `Value` = '{0}' WHERE `Property` = '{1}'", value, name);
}
}
}
}
Then from my application
string msiVersion = PropertyTable.Get("MyInstall.msi", "ProductVersion");
You can use Orca to view the msi tables. MSDN provides documentation on the Property Table. The details on SQL syntax for Windows Installer is also available in MSDN
