Dot Net Framework V 4.0 3019 Offline Installer

[Tancredo Dori]

Iwas trying to test our products to make sure that they are compatible with Windows Server 2016. And during some testing, I mistakenly thought that I can simply "downgrade" .NET framework from 4.6 to 4. So I removed .NET 4.6 from Roles and from IIS.

Now, I can't install it back using installer (because its part of OS so it is asking me to enable it from role & features). And I can't start server manager (to install role & features) because it needs .Net 4 at minimum.

My problem:On Windows Server 2016, the .NET Framework 4.6 had been inadvertently uninstalled from my system while trying to fix some issues with IIS. It was removed using the Server Manager > Remove Roles and Features.

As a result, the Power Shell, Server Manager, and Event Viewer were no longer working. So I downloaded and installed the latest offline version of the .NET Framework 4.7 from Microsoft using the installer. However, it did not fix the problem when installed by clicking on the installer.

SolutionTo fix the problem, I had to install it from the command line using the "/all" switch. I unzipped the installer to a folder and here is the command that I used to install it. In the last argument in quotes is the path to the installer, which will need to be modified based on where you have the installer unzipped:

@Yoann same issue here. Clean install of Windows Server 2019 latest build, install .NET Framework offline installer 4.8, reboot and boom. Many native control panels, like Server Manager, requesting some 4.0.... version of .NET framework instead, failing to load.

I had the same issue and received zero help or support from Microsoft. Dell support googled and read back to me everything I had googled and tried already. Importing the above registry information fixed it without a reboot.

@DavidSherrill This is the exact fix! For us, our RMM tool stopped working on a server 2019 standard server. It's services wouldn't start. Event Viewer complained about .net. Also server manager wouldn't open with the exact message you mentioned. Applying this fixed it all. thanks!!

YOU ARE AN ABSOLUTE LEGEND! THANK YOU! THIS IS THE ONLY SOLUTION THAT WORKED! Every other solution I've googled of this problem has been some variation of "turn net framework on/off in the "turn windows features on or off" app" or "reinstall the newest version of .net" or "did you try restarting your computer?" (OF COURSE I TRIED RESTARTING MY COMPUTER!! DO THEY THINK I'M AN INFANT??)

Please excuse my novice status displayed in this question, but does one simply copy/paste the text in your registry update file, and does the resulting text file require the line number entries as displayed in your post?

I am trying to install .net framework 3.5 onto windows server 2019 that is offline. I have downloaded the offline installer dotnetfx35.exe but I get an error when trying to install the exe when double clicking on it. Any advise online says to use the windows ISO but I do not have it. Is there anyway you can use the offline installer of dotnetfx35.exe on windows server 2019?

Microsoft released the final version of the Microsoft .NET Framework 4.8 on April 18, 2019. The new installer for the version is available as a web installer and offline installer; since Microsoft prefers distribution via the web installer, it is difficult to find working offline installer links. You find a working offline installer link attached to this article.

The changelog on the Microsoft Docs website highlights new features and changes in the new release. The log is quite technical in nature and intended for programmers who use the framework more than it is for Windows users and administrators who install it.

New features in .NET Framework 4.8 include high-DPI improvements such as improved support for Windows Forms interoperation in high-DPI WMF applications on platforms that support mixed-mode DPI scaling or support for Per-Monitor V2 DPI Awareness.

The .NET Framework is offered as a Web and Offline installer. The core difference is that the Web Installer requires an active Internet connection during installation as it needs to download components from Microsoft servers.

Check out the following link to download official .NET Framework 4.8 Language Packs for offline installation. The language packs include translated error messages and user interface text; the text is displayed in English if no language pack is installed. Microsoft lists 23 different language packs currently that include languages such as Chinese, Arabic, German, Spanish, Italian, Japanese, Dutch, Portuguese and Russian.

"Improvements to the JIT compiler. The Just-in-time (JIT) compiler in .NET Framework 4.8 is based on the JIT compiler in .NET Core 2.1. Many of the optimizations and all of the bug fixes made to the .NET Core 2.1 JIT compiler are included in the .NET Framework 4.8 JIT compiler."

Microsoft started development on the .NET Framework in the late 1990s originally under the name of Next Generation Windows Services (NGWS). By late 2001 the first beta versions of .NET Framework 1.0 were released.[1] The first version of .NET Framework was released on 13 February 2002, bringing managed code to Windows NT 4.0, 98, 2000, ME and XP.

Since the first version, Microsoft has released nine more upgrades for .NET Framework, seven of which have been released along with a new version of Visual Studio. Two of these upgrades, .NET Framework 2.0 and 4.0, have upgraded Common Language Runtime (CLR). New versions of .NET Framework replace older versions when the CLR version is the same.

The .NET Framework family also includes two versions for mobile or embedded device use. A reduced version of the framework, the .NET Compact Framework, is available on Windows CE platforms, including Windows Mobile devices such as smartphones. Additionally, the .NET Micro Framework is targeted at severely resource-constrained devices.

.NET Framework 4.8 was announced as the final version of .NET Framework, with future work going into the rewritten and cross-platform .NET Core platform (later, simply .NET), which shipped as .NET 5 in November 2020.[2][3] However, .NET Framework 4.8.1 was released in August 2022.[4]

The first version of the .NET Framework was released on 15 January 2002 for Windows 98, ME, NT 4.0, 2000, and XP. Mainstream support for this version ended on 10 July 2007, and extended support ended on 14 July 2009, with the exception of Windows XP Media Center and Tablet PC editions.[14]

.NET Framework 1.0 is supported on Windows 98, ME, NT 4.0 (with Service Pack 6a), 2000, XP, and Server 2003. Applications utilizing .NET Framework 1.0 will also run on computers with .NET Framework 1.1 installed, which supports additional operating systems.[36]

Version 1.1 is the first minor .NET Framework upgrade. It is available on its own as a redistributable package or in a software development kit, and was originally released on 9 April 2003. It is also part of the second release of Visual Studio .NET 2003. This is the first version of the .NET Framework to be included as part of the Windows operating system, shipping with Windows Server 2003. Mainstream support for .NET Framework 1.1 ended on 14 October 2008, and extended support ended on 8 October 2013. .NET Framework 1.1 provides full backward compatibility to version 1.0, except in rare instances where an application will not run because it checks the version number of a library.[40]

The .NET Framework 1.1 Service Pack 1 was released on 30 August 2004.[43] It requires Windows NT 4.0 SP6a plus Windows Installer 2.0. It is the last version to support Windows NT 4.0 SP6a, Windows 2000 RTM-SP2 and Windows XP RTM-SP1.

Version 2.0 was released on 27 October 2005. It was also released along with Visual Studio 2005, Microsoft SQL Server 2005, and BizTalk 2006. A software development kit for this version was released on 29 November 2006.[44] Support ended on 12 July 2011. It is the last version to support Windows 98, Windows 2000 SP3, Windows ME and Windows Server 2003 RTM.[45]

.NET Framework 2.0 is supported on Windows 98, ME, 2000 (with Service Pack 3 or higher), XP (with Service Pack 2 or higher), Server 2003, Server 2008 and Server 2008 R2.[6] An unofficial backport for Windows 95 was created in 2024.[18][46] Applications utilizing .NET Framework 2.0 will also run on computers with .NET Framework 3.0 or 3.5 installed, which supports additional operating systems.

The .NET Framework 2.0 Service Pack 2 was released on 11 August 2008.[48] It requires Windows 2000 with SP4 plus KB835732 or KB891861 update, Windows XP with SP2 plus Windows Installer 3.1. It is the last version to support Windows 2000 SP4 although there have been some unofficial workarounds to use a subset of the functionality from Version 3.5 in Windows 2000.[49]

.NET Framework 3.0, formerly called WinFX,[50] was released on 6 November 2006. It includes a new set of managed code APIs that are an integral part of Windows Vista and Windows Server 2008. It is also available for Windows XP SP2 and Windows Server 2003 as a download. There are no major architectural changes included with this release; .NET Framework 3.0 uses the same CLR as .NET Framework 2.0.[51] Unlike the previous major .NET releases there was no .NET Compact Framework release made as a counterpart of this version. Version 3.0 of the .NET Framework shipped with Windows Vista. It also shipped with Windows Server 2008 as an optional component (disabled by default).

.NET Framework 3.0 is supported on Windows XP, Server 2003, Vista, Server 2008, and Server 2008 R2.[6] Applications utilizing .NET Framework 3.0 will also run on computers with .NET Framework 3.5 installed, which supports additional operating systems.

Version 3.5 of the .NET Framework was released on 19 November 2007. As with .NET Framework 3.0, version 3.5 uses Common Language Runtime (CLR) 2.0, that is, the same version as .NET Framework version 2.0. In addition, .NET Framework 3.5 also installs .NET Framework 2.0 SP1 and 3.0 SP1 (with the later 3.5 SP1 instead installing 2.0 SP2 and 3.0 SP2), which adds some methods and properties to the BCL classes in version 2.0 which are required for version 3.5 features such as Language Integrated Query (LINQ). These changes do not affect applications written for version 2.0, however.[55]
