Error when trying to install Microsoft SQL Server 2019, Express edition.

Question

Hello, I am trying to reinstall Microsoft SQL Server 2019 but I get the error below. I had installed it before on my laptop and uninstalled it. Now trying to reinstall and it gives this error "Oops, a required file could not be downloaded. This could mean the version of the installer is no longer supported. Please download again from the download site"...

Answer 1

From your explanation I would like to ask you if you used the previous downloaded version of the installer or got a complete fresh one from the download page?

As the error message states „the version of the installer is no longer supported“ maybe there are some minor version between your previous downloaded version and the actual one… so that they do not work anymore…

Please try a fresh download of the installer and give it a try, if that’s nothing you already tried.

Answer 2

Hi @Eno Udobi ,

Welcome to Microsoft Q&A!
The first thing you should do is to determine if it is a problem with the version not being supported. Please see this document about it: Operating system support.
So if you are on a very old operating system, it just doesn't support installing this version of SQL Server.
Secondly, if you are using the correct version, it may be that your download file is corrupt or that there is a problem with the download location.
Could you try to change the network or another disk to store that file? Or you can download the file from another machine and copy it to this machine.

Best regards,
Seeya

It has something to do with TLS and new Windows Updates, here is a solution from another forum.

Open PowerShell as administrator and run

Set-ItemProperty -Path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type Dword
Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft.NetFramework\v4.0.30319' -Name 'SchUseStrongCrypto' -Value '1' -Type Dword
