Hi Akshay Hebbar,
Troubleshooting Steps for SQL Server 2019 Installation Issue
It looks like the SQL Server 2019 installer is detecting remnants of a previous SQL Server installation. This usually happens when uninstall didn’t fully remove all components. To fix this:
- Uninstall old SQL Server components via Control Panel → Programs and Features. Remove all entries related to SQL Server, SQL Server Management Studio, and SQL Native Client.
- Stop and delete leftover services in services.msc (e.g.,
SQL Server (MSSQLSERVER),SQL Server Agent). - Delete SQL Server folders from:
-
C:\Program Files\Microsoft SQL Server -
C:\Program Files (x86)\Microsoft SQL Server -
C:\ProgramData\Microsoft SQL Server
-
- Clean registry keys under:
-
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server -
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SQL Server(be careful to only remove SQL Server–related keys)
-
- If manual cleanup is tricky, use the SQL Server Installation Cleanup Tool or run the installer in Repair/Remove mode.
- After cleanup, rerun
setup.exeas Administrator and choose New SQL Server and installation.
Thanks,
Lakshmi.
