I'm using the Microsoft.Deployment.WindowsInstaller
libraries to read out values from a .msi file. Properties are no problem, and the summary-information can also be read out, example:
static void Main(string[] args)
{
using (var database = new QDatabase(@"C:\myMsi.msi", DatabaseOpenMode.ReadOnly))
{
Console.WriteLine(database.ExecutePropertyQuery("ProductVersion"));
Console.WriteLine(database.ExecutePropertyQuery("ProductName"));
Console.WriteLine(database.ExecutePropertyQuery("Manufacturer"));
Console.WriteLine(database.ExecutePropertyQuery("ARPREADME"));
}
}
The QDatabase
object even has a nice SummaryInfo
property, holding the summary information. However, I haven't found out how to get the platform for which the .MSI is intended for.
It would seem that platform can be read out, as Orca also does this (the platform can be seen when opening the Summary Information in Orca).
How can I get the platform for which the .msi was intended?
You are using a class that is meant to do LINQ queries of the database. ExecutePropertyQuery is a method that simplifies querying the Property table. As you noted the information you seek isn't in the property table, it's in the Summary Information Stream. Specifically:
Template Summary property
using Microsoft.Deployment.WindowsInstaller;
using(Database database = new Database(PATH_TO_MSI, DatabaseOpenMode.ReadOnly))
{
Console.WriteLine(database.SummaryInfo.Template);
}
The QDatabase class also exposes the SummaryInfo property also as it extends the Database class.
Queryable MSI database - extends the base Database class with LINQ query functionality along with predefined entity types for common tables.
