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 :-)

    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

    Hi @MJ Skeet,

    Please try to install .Net Framework v.4.8

    Since you've already tried installing different versions of .NET Framework, it's possible that the installation is getting blocked by a Windows security feature. To resolve the issue, try the following:

    1. Right-click the SQL Server 2022 setup file and choose "Properties."
    2. In the "General" tab, click "Unblock" if it's available, then click "Apply" and "OK."
    3. Re-run the SQL Server 2022 setup.

    This should allow the installation to proceed without the .NET Framework error.
