I have installed SQL Server 2022 Developer edition successfully on a Windows 10 and 11 virtual machine. The issue is that I cannot install it on a physical machine. During the install, I get the following fatal error. I have tried to install the latest .NET Framework, and my OS says it's already installed. I tried to install 4.0 .NET and the message is that it's included with my installed version. I tried to install 2.0 .NET framework, and the installer doesn't launch. The error's help link is dead. I've attached the log file.2023-03-22_10-36-55

    I got it to work by right-clicking on setup.exe and running as administrator.

    For me rebooting my system and then reinstall SQL server 2022 Ex Ed (by right clicking and select 'Run as admin') helped :-)

    For me, the following helped:

    On the installation media, locate the file SQLSUPPORT.msi (in folder 1033_ENU_LP\x64\setup) and execute it manually once. After that, restart the setup and it should complete as expected.

    Many thanks for your quick and thorough responses! Thank you so much. I've tried everything you listed, here are the results. Sadly, none worked.

    • The "unblock" option was not available to me.
    • The .NET version installed is 4.8.04084
    • I went through the five different ways to repair .NET Framework (except for the Powershell option, as I kept getting format errors on the command).
    • I have only been installing with the SQL Server Installation Center. I missed the fact that the installer passes the .NET Framework check, and then fails with a .NET error. Feels like an installer bug to me. See the screenshot.
    • The system says Windows updates are up to date, but I forced a check anyway, and there were no more updates. I'm still at a loss. Do you have any other ideas?2023-03-27_8-24-19
