Hi, That message is actually asking for .NET 2.0 Service Pack 1. Alternative you can install .NET 2.0 Service Pack 2 as it includes the Service Pack 1. Having .NET 4.0 doesn’t help as it doesn’t contain .NET 2.0. So in short, installing either Service Pack 1 or Service Pack 2 for .NET 2.0 is all you need. Thanks, Alex
