help, i can finish instaling SQL because of this erro, can someone help me with it
The error code tells us nothing. In the folder C:\Program Files\Microsoft SQL Server\nnn\Setup Bootstrap\Log, you find one folder per installation attempt. The files of most interest are summary.txt and detail.txt. Feel free to upload them here. nnn is a three-digit number which depends on which version of SQL Server you are trying to install. For SQL 2025, the number is 170.

To help you we need the o/s and version, the Sqlserver version and edition, the hardware type (intel, arm) , but mostly the actual error message in the log.
the most common install errors we see are are disk sector size too large, or install on arm64. For arm64 only docker installs are supported and docker must be configured for amd64 emulation (Mac docker has years of support, but windows docker support is recent).

Hi @NGUYỄN MINH ĐỨC ,
The exit code itself is not useful the logs are the key. Once you identify and fix the specific error from Summary.txt or Detail.txt, the installation should complete successfully.
If you can share the log details, it’s possible to pinpoint the exact issue quickly.
Thanks,
Akhil.
Hi @NGUYỄN MINH ĐỨC ,
Hi, just checking in were you able to review the Summary.txt or Detail.txt logs? If you can share the error details from those files, we can help identify the exact issue and get your installation working.
Thanks,
Akhil.
Exit code -2147467259 during SQL Server installation is a generic failure code. From similar reported cases, this typically indicates that the Windows/SQL setup environment is in a bad or inconsistent state that is difficult to repair directly.
A practical way forward that has been recommended in this situation is:
This approach bypasses the corrupted/complex state of the current OS and gives a clean, reproducible environment for learning and development.
If choosing to repair the current machine instead, review the SQL Server setup logs under the Setup Bootstrap\Log folder and correlate with the specific error patterns described in the SQL Server installation troubleshooting articles in the references.
