If you want help with something, you should post a new question, not piggyback on an old thread. For a Setup problem include the log files summary.txt and detail.txt. You find these in C:\Program Files\Microsoft SQL Server\nnn\Setup Bootstrap\Log where there is one folder per installation attempt.

The message Wait on the Database Engine recovery handle failed is a generic error that means that SQL Server did not start when Setup wanted to run configuration steps. To understand why it did not start, you need to look in the SQL Server errorlog, which you find in C:\Program Files\Microsoft SQL Server\MSSQL16.SQLEXPRESS\MSSQL\LOG\ERRORLOG. Note that the component MSSQL16.SQLEXPRESS assumes a default installation SQL 2022 Express. If you are trying to install an older version or a named instance, this component will have a different name.

If you see a message about 256 misaligned reads, you are running into a known issue where Windows 11 for some disk drives reports a sector size that SQL Server does not cope with. Microsoft has published an article with workarounds for the problem.

If you don't see the message about misaligned reads, feel free to upload the errorlog here, so we can look at it. You will need to rename to ERRORLOG.txt for the forum software to accept it.

Hi @Erland Sommarskog ,

Thanks @Erland Sommarskog for your valuable inputs. If that message isn’t there, try the following quick checks before reinstalling:

Restart your computer – setup may fail if a prior install left a pending reboot.

Run the installer as Administrator (right-click → Run as administrator).

Temporarily disable antivirus or Defender real-time protection – they can prevent the SQL service from starting.

Ensure Windows Updates are fully installed – pending updates can block service startup.

Verify enough free space on the system drive (at least 6–8 GB recommended).

No. A pending reboot blocks setup from starting.

Run the installer as Administrator (right-click → Run as administrator).

Setup requests to be administrator. And if admin rights are the problem, they occur later in the process. Note that this error comes towards the end of the installation, when Setup tries to start SQL Server.

Temporarily disable antivirus or Defender real-time protection – they can prevent the SQL service from starting.

Please only suggest disabling anti-malware software if there is a clear indication that this is actually causing setup to fail. There is the risk that the person you give this advice follow it - and then forget to re-enable the antivirus.

Overall, there is no reason to suggest random things to try, when we know that the problem is that SQL Server does not start. At this point, we should always get more information on why it does not start. Random troubleshooting actions that are irrelevant to the problem are more likely to make matters worse than to be helpful.

Hi @Erland Sommarskog ,

Thanks for the clarification that’s a great point. I appreciate you highlighting that the issue occurs after setup starts the Database Engine and that it’s better to focus on reviewing the ERRORLOG for the exact cause rather than suggesting general troubleshooting steps. Thanks for the detailed explanation and guidance.

Thanks,
Akhil.
