My application is not working on AMD CPUs

Question

I have created a Winforms application in .NET Framework 2.0 in Visual Studio 2005 in C#.

The application uses the following references on x64:

MS Visual Studio C++ 2005 Redistributable (x64)

MS Visual Studio C++ 2005 Redistributable

and for X86

MS Visual Studio C++ 2005 Redistributable

for Crystal Reports. The references are inside the setup.exe.

I tried to install the app on a PC with AMD processor and Windows 10, but the application (splashscreen) does not even start.

My first form is a simple SpashScreen:

private void DoSplash()
{
            SplashScreen sp = new SplashScreen();
            Application.Run(sp);
}
public Main()
{
            InitializeComponent();
            InitializeComponent2();
            ...
            Thread th = new Thread(new ThreadStart(DoSplash));
            th.Start();
            Thread.Sleep(3000);
            th.Abort();
            ...
            //checking for new update
}

Do I need to change something in Visual Studio ?
