How to fix Sql Server installation error on my windows 11

Question

Hi, I'm unable to install SQL Server 2022 on my windows 11. When I make an effort to do so, it results in a message stating unable to install SQL Server (setup.exe). Exit code (Decimal) -2147467259 Error description: Unknown error (0xe0000235). I saw that the database engine service failed in the summary text file.

Hi @Kiodore,

There is a known issue when installing SQL Server on Win11.

You may follow the documentation to see if it is helpful.

If this does not work, you may follow the steps to uninstall the failed installation and reinstall it.
Please follow the below steps to remove all components of previous installed SQL Server completely:

1. Remove all SQL Server components from 'Programs and Features'
2. Backup the registry
3. Delete the following keys in regedit:
   --HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server
   --HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer
4. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and delete all the sub-keys referencing SQL Server
5. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and delete all the keys referencing SQL Server
   6. Reboot the machine
   In addition, please use an administrator account to reinstall SQL Server on your computer(Right click->run as administrator).
