Hi,
We are using a keysight application that requires .net framework 4.0. when we tried to install it says it a part of the OS or a higher version has been installed.
we are using windows 10 20h2. when we launch the application it crashes immedialtely. Please find the below screenshot.
Please help to resolve the issue.
Best Regards,
Giri.
Did you also contact the manufacturer’s Support?
If they cannot help or upgrade the application, then maybe go to Settings and make sure that your Windows includes all of updates. However, .NET Framework 4.0, released in 2010, seems obsolete.
You can also install the latest recommended .NET Framework 4.8.
Consider restarting the computer too.
Why do you think that it is a clr.dll issue? Make sure that you do not replace it with an inappropriate or suspicious file.
Do you use a third-party antivirus instead of the default one? (Sometimes, the problems are caused by antivirus software).
Ok, no we use only windows defender.

Go to "Control Panel"
click "Programs"
click "Program and Features"
In left pane select "Turn windows features on or off"
windows features Tab opens,
select ".NET Framework 4.0" and (check the box is select),
then click ok..
now try the app now...

@PraveenPouloseE-9605: I tried earlier, it didn't work.
go to programs and uninstall .NET framework all versions and restart then install 4.0 net framework.
Tried uninstalling and installing one by one but no luck.
Tried windows update.
Yes, How to fix the clr.dll issue? I think the issue is with dll file.
https://www.dll-files.com/clr.dll.html
go to this link and download the file and extract the dll file and copied to mentioned folder.
Read below article and do that step
I tried but it gives an error while registering dll.

@Giri
Is your question like the one below?
Error: "Microsoft .NET Framework 4 is already a part of this operating system. You do not need to install the .NET Framework 4 redistributable". While installing .NET Framework.
It may be that this application can only use .Net Framework 4 for some reasons, but Windows 20H2 only has an updated .Net Framework built in.
In that case, it might be better to post a question in the Microsoft Community asking how to install the old .Net Framework. This is really beyond the scope of the problem that programming can solve, we can only provide some guesses.
