Windows Server 2019 and .NET 4.8?
Hello,
On a fully updated Windows Server 2019, roles and features allow me to install only .NET 4.7.
One of the solution we are using require .NET 4.8 (Adaxes).
When I install .NET 4.8 using the installer available here https://support.microsoft.com/en-us/topic/microsoft-net-framework-4-8-offline-installer-for-windows-9d23f658-3b97-68ab-d013-aa3c3e7495e0
It works, I can install Adaxes, but it break ServerManager as well as Azure AD Connect.
What's the correct procedure to install .NET 4.8 on Server 2019 without breaking anything else?
Thanks a lot
- I ran into this issue after the Windows Update, Cumulative Update for .NET Framework (KB5006765), was installed on a Windows Server 2019 that also had Azure AD Connect installed. Apparently, a bunch of .NET registry items where deleted. Server Manager and any software built on .NET was not working...throwing this error:
This application requires one of the following versions of the .NET Framework: v4.0.30319
Do you want to install this .NET Framework version now?
DSIM and SFC repairs did not work, nor did rolling back the Windows Update.
Found some insight here:

Ended up having to import these registry items from a working system:

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v4.0.30319\SKUs\DefaultYou sir, are a gentleman and a scholar. Thanks for the information.
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.
- Thank you man, you saved my life! After hours of hard work I saved your registry keys to a .reg file, write a "Windows Registry Editor Version 5.00" string to it's header and successfully import it. Server Manager is working again and I'm able to start all broken services again!
- I just wanted to add my thanks as well as I was having a hard time finding the resolution to this issue until I found your post. Here here!
- Genuis! I don't know who originally solved this, but your solution worked, thanks very much. After many hours of repairing .NET, rebooting and getting the same error, going around in circles I eventually found this post and it worked. Thanks!

I figured out the solution to copy .net registry settings from a working computer back in march '22 after working the problem sweating bullets for hours myself trying to fix our tertiary ADC-server. Luckily the primary and secondary were not hit with the same problem.No amount of uninstalling/installing fixed it.
But "simply" export the reg keys from a working computer and import them in the broken server, and that worked. A restart is always a good idea to ensure everything starts up properly.
I'm mortified that Microsoft still haven't fixed the problem/issue... that it is still occurring even now!
The original problem-poster (User named: action-undo-balance) of the BleepingComputer forum mentioned this as the potential cause of the problem:After many many hours of research on this I've gotten to the bottom of this. The issue is this TLS 1.2 enforcement script:
Only a few days ago this script was different - it wasn't wrapped in that "if" statement. You can see the commit here:
The problem is this line:
New-Item 'HKLM:\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v4.0.30319' -Force | Out-Null
Which creates that path (if it doesn't exist). If it does exist (which it does by default on Server 2019) it empties it.
Microsoft could probably fix the problem by changing the installer to always recreate those redirects for earlier versions of .net.
- How did you get the offline installer for 4.8.1 to work?
- offline installer for 4.8 works fine, but the offline installer for 4.8.1 says it's not supported. It's an old app, I'll just stick to 4.8.
- no me quedare con l version actual
