Unable to install MS SQL Server 2019 Express

Question

I tried almost everything I found online. I reinstalled drivers for SQL Server but again the same message when I run SQL Server Express installation:
"Ooops... A required file could not be downloaded. This mean that version of the installer is no longer supported. Please download again from download site: forward link". And again the same message when I downloaded and started "new" version of the installer (quoted new because I downloaded that installation which displayed me that message couple of minutes ago). I'm pretty much stuck here. How to solve this?

Answer 1

Hi @Marko Stojanovic ，

Please try to add a backslash between Microsoft and .NetFramework in the registry:

 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
