Net Framework 4.0 Redistributable 64 Bit

Support lifecycle: Mainstream support ended January 13, 2016; Extended support ended January 13, 2019.

When installed on a 64-bit OS, the redistributable deploys the following critical components:

| Component | Path (x64) | Purpose | |-----------|------------|---------| | 64-bit CLR | %windir%\Microsoft.NET\Framework64\v4.0.30319\ | Core execution engine – different from x86 CLR | | NGEN | %windir%\Microsoft.NET\Framework64\v4.0.30319\ngen.exe | Native image generation for x64 | | MSBuild | %ProgramFiles(x86)%\MSBuild\14.0\bin\amd64\ | 64-bit build tasks | | GAC (64-bit) | %windir%\Microsoft.NET\assembly\GAC_64\ | Stores 64-bit assemblies separately from GAC_32 and GAC_MSIL | | Registry | HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 (64-bit view) | Configuration for x64 runtime | net framework 4.0 redistributable 64 bit

Open PowerShell (64-bit) and run:

Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full' | Get-ItemPropertyValue -Name Release

Also check directory:

dir "C:\Windows\Microsoft.NET\Framework64\v4.0.30319\clr.dll"

The Microsoft .NET Framework 4.0 Redistributable (64-bit) is a critical software component that provides the Common Language Runtime (CLR) and base class libraries required to execute applications built for .NET Framework 4.0 on 64-bit Windows operating systems. While functionally stable, it is technically obsolete and has been superseded by newer, backward-compatible versions (.NET 4.5, 4.6, 4.7, 4.8). New deployments should target .NET Framework 4.8 unless legacy application constraints mandate version 4.0. Support lifecycle : Mainstream support ended January 13,
