    I have researched this a little more, and it's apparently the case that Microsoft has broken something. You may want to wait a few days to come back and download a new version of the installation program. (I tried both the current download as well as an old download. The old one works. The new one produces the error above directly when I start it.)

    It seems that running these updates to the registry fixes the issue:

    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

    Note there are some versions of this script out there with a backslash missing, so make sure you use the above.

    There were a lot of people who had problems with this error one day last week, and then there was nothing the next day. Seems like Microsoft changed something and then changed it back.

    In any case, I would recommend that you select the option "Download Media", as this if nothing else simplifies diagnostics.

    I noticed that you also posted to this thread: https://learn.microsoft.com/en-us/answers/questions/464840/unable-to-install-sql-server-2019-developer-versio.html?childToView=813779. That thread actually has some resolution to this error that worked for the issue last week. You could try these if Download Media does not work.

    "Download Media" - I didn't understand can you elaborate.

    When you start the exe you downloaded, your are looking at this screen:


    My suggestion was that you would try the rightmost alternative.

    can any one from Microsoft community take remote access to my lap and resolve my issue ? I am SQL developer (employee)

    I can't speak for anyone else, but I'm afraid that I am not willing to spend time on thing like this. Not the least when this may be due to something in your environment, as set up by your IT department. And speaking of your IT department, I can't imagine that they would permit outsiders to connect to company laptops.

    Rather I think you should speak to your IT folks. Maybe they already have the media available and you can get it from them.
