Net Framework 4.0 Redistributable 64 Bit !!link!! -

: Version 4.0 was the first to truly harness multi-core processors through the Task Parallel Library (TPL) Parallel LINQ (PLINQ)

32-bit applications are limited to 2 GB of virtual memory. If you are running a legacy scientific simulation or data processing tool built on .NET 4.0, the 64-bit redistributable is mandatory to process large datasets without hitting an OutOfMemoryException . net framework 4.0 redistributable 64 bit

Additionally, .NET 4.0 introduced significant enhancements to the CLR itself, most notably "Code Contracts." This feature allowed developers to specify pre-conditions, post-conditions, and object invariants in their code, leading to more robust and bug-free software. For the 64-bit user, these improvements meant that applications were not only capable of using more memory but were also generally more stable and secure. Furthermore, the 4.0 release improved the deployment experience; it was designed to be side-by-side compatible with older frameworks (like 3.5), reducing the "DLL Hell" conflicts that often plagued earlier Windows systems. : Version 4
