Problems installing ART with Scream on Windows 10
If you choose to install ART 3 along with Scream on a Windows 10 PC, you may see an error message saying that the .NET Framework is not installed. This can be misleading because it can occur even when the one or more versions of .NET are are already installed.
The error arises because ART 3 depends on a version of the MatLab™ Compiler Run-time (MCR) which, in turn, depends on the .NET 3.5 Framework. Recent versions of Windows 10 include other versions of .NET, but not 3.5. Fortunately, it is easy to download and enable the required version alongside any other version which may be installed. This can be done without affecting other programs which may rely on different versions. This document explains how.
