The Microsoft .NET Framework 4.7 is a highly compatible, in-place update to the Microsoft .NET Framework 4, 4.5, 4.5.1, 4.5.2, 4.6, 4.6.1, and 4.6.2. The offline package can be used in situations where the web installer cannot be used due to lack of internet connectivity.
.NET Framework 4.7 WPF features take a dependency on D3DCompiler_47.dll . This D3DCompiler_47.dll is not present by default in Windows 7 SP1, Windows 2008 R2 SP1 and Windows 2012 OS platforms. Hence these OS platforms require D3DCompiler_47.dll to be installed for .NET Framework 4.7 WPF features to work as expected. Please see known issues article for D3DCompiler_47.dll install information details.
