.NET 4.5 Application does not start with only .NET 4.7 installed

Question

I have a C# .NET WPF (MVVM Lite) Application that runs on Windows 7 machines. It is combiled for .NET 4.5.

While .NET 4.5.2 was installed on the clients, it run as it should. After an client update to .NET 4.7 and uninstalling .NET 4.5.2 (!) the application hangs on start:

Frameworkversion: v4.0.30319 Beschreibung: DThe process was terminated by an unhandled exception. exception information: System.Runtime.InteropServices.COMException bei MS.Win32.Penimc.UnsafeNativeMethods.CoCreateInstance(System.Guid ByRef, System.Object, Int32, System.Guid ByRef) bei MS.Win32.Penimc.UnsafeNativeMethods.CreatePimcManager() bei MS.Win32.Penimc.UnsafeNativeMethods..cctor()

App.xaml.cs is modified:

public partial class App : Application, ISingleInstanceApp 
{

    private static string Unique = "Test_xx";

    [STAThread]
    public static void Main()
    {    
        for (int i = 1; i < Environment.GetCommandLineArgs().Length; i++)
            Unique += Environment.GetCommandLineArgs()[i];

        if (SingleInstance<App>.InitializeAsFirstInstance(Unique))
        {
            var application = new App();
            application.InitializeComponent();
            application.Run();

            // Allow single instance code to perform cleanup operations
            SingleInstance<App>.Cleanup();
        }
    }

    public bool SignalExternalCommandLineArgs(IList<string> args)
    {
        if(args.Count < 3 || args[2].ToUpper() != "AUTOSTART")            
            MessageBox.Show("Program already runs!","Error!",MessageBoxButton.OK,MessageBoxImage.Warning);

            Current.MainWindow.WindowState = WindowState.Maximized;                
            return true;
    }

    protected override void OnStartup(StartupEventArgs e)
    {            
            this.StartupUri = new System.Uri("MainWindow.xaml", System.UriKind.Relative);


    }

Any ideas?

@MikeT Thank you for the link. But the application (binaries) did not change for over 1 month. The issue came over night (last week). — Matthias G, Jun 26 '17 at 10:58
