An embedded UI handler cannot call custom actions directly. The Session object you get in the IEmbeddedUI.Initialize() handler is only a limited session which lets you get/set properties and not much else (there's no database either). The limitations are imposed by MSI's embedded UI design, not DTF. But I'm afraid MSI embedded UI is not very well-documented on MSDN.

I added a dll in the Binary table and tried to read it in the class that implements IEmbeddedUI : object result = session.Database.ExecuteScalar("select Data from Binary where Name = '{0}'", "CustomDialogs"); and I get an Microsoft.Deployment.WindowsInstaller.InvalidHandleException. >From what I saw in the debugger, this exception appears in Database.CodePage. Looking in the source file for DTF it goes to Database.Export(string table, string exportFilePath) . It seams that the Handle is closed. The same happends if I try to call a custom action from the class that implements IEmbeddedUI : session.DoAction("MyCustomAction"); // throws InvalidHandleException Did anyone encounterd this exception also ?
