Software That Is Automatically Installed
.NET Framework
On most versions of Windows, the .NET Framework 4.6.2 is automatically installed.
Microsoft Visual C++ Redistributable 2017
Starting with Service Pack 18, Microsoft Visual C++ Redistributable 2017 (vcredist2017.exe) is automatically installed.
If a computer does not have the most recent Windows updates, the installation of Microsoft Visual C++ Redistributable 2017 will fail in installing Universal C Runtime. The following Windows updates must be installed to prevent the installation failure. The updates are not required on the most recent Windows operating system versions, such as Microsoft Windows 10 and Microsoft Windows Server 2016, because these versions have the Universal C Runtime already installed.
