Windows components do not have Microsoft .NET Framework 4, how do I enable/reinstall it?

Question

System administration

I use Windows 10, previously I installed docker, everything worked, then I deleted it, now I had to install it again, at startup it gives an error:

Docker startup error

---------------------------
Docker Desktop.exe - Ошибка инициализации платформы .NET Framework
---------------------------
Для запуска этого приложения сначала необходимо установить одну из следующих версий .NET Framework:

  v4.0.30319

 Обратитесь к издателю приложения за инструкциями по получению соответствующей версии .NET Framework.

ОК

* the version of the requirement has changed, it used to be like 4.5-4.8, because. I *spoiler* demolished all versions of .net framwork later

After walking around the problem for half a day, I downloaded the .NET Framework installer, but it refuses to install, referring to the fact that the .NET Framework 4 is already installed

Installation error screen

Googling some more, I opened Windows components, where it should be the following:

What should be (screenshot from the Internet)

But I do not have a tab with .NET Framework, but only this:

My screen

When you try to include everything where there is .NET, when you re-open this menu, the daws fly off. Sometimes after installing the checkboxes, it asks for a reboot, and sometimes not, but this does not affect anything.

After googling this problem, I downloaded the .NET Framework Cleanup Utility, where the item "delete all versions of Windows 10" was selected, as a result, as everyone already understood, I demolished all versions, that now some programs refuse to work for me, including PowerShell .

As a result, as I thought, if I delete everything, then I can easily roll over .NET Framework 4 and other versions, but unfortunately the screen with an installation error is still relevant and asks to enable it in the components, but it is not there.

If you check the list of installed .NET Framewrok in the system, it shows that they are (even though I removed them)

List of frameworks in the registry

I have already completely given up, and I don’t know where to look for answers, Google along and reproached me, so the last hope is here.

Answer 1

Try the .NET Framework Repair Tool.

Answer 2

Try deleting the Release parameter from the branch from the registry

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full

and run the installation again. Just make a copy of the branch first :)
Another option is to run the installer with the /repair option (maybe this only works with the full, offline installer).

Answer 3

4.0 cannot be set to 10 because it implies built-in either 4.6 or something else.
Try to roll fresher - 4.8
And find a fresher docker, maybe it just doesn't fit your version of Windows

Answer 4

Install .NET 5.0 right away .
Even if there are some problems with the current framework, they will be fixed.

Answer 5

With the SetWindowPos function . Something like this:

with TForm1.Create(self) do
begin
  Show;
  SetWindowPos(Handle, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOACTIVATE + SWP_NOMOVE + SWP_NOSIZE);
end;
