SQL Server 2019 Developer Edition - Download failed

Question

I am receiving an error when trying to run the SQL Server 2019 Developer Edition executable file.

Error A required file could not be downloaded. This could mean the version of the installer is no longer supporter

I have searched online again and again and any of the solutions posted did not rectify the error.

Answer 1

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

Answer 2

Hi OBrienCianJNJIENONJJ-2803,

It might be TLS issue. Please check if the TLS 1.0 is enabled in SCHANNEL.
Please refer to this similar thread which might be helpful.
