Microsoft has retired the official .NET 4.0 download pages. Your best bet is:

This specific build (4.0.3019) is a critical update to Microsoft’s .NET Framework 4.0 Full package. It is not the newer 4.5, 4.6, or 4.8 versions. Many legacy applications (especially CAD software, ERP systems from 2010–2015, and certain medical or financial tools) explicitly check for this exact build number. Without it, they will refuse to install or run. net framework 4.0 3019 download windows 7 offline installer
