    Hi @Dave Budah,

    Please try to launch the SQL Server Setup program (setup.exe) as administrator from SQL Server installation media-> Maintenance in the left-hand navigation area-> Repair.User's image

    You can try to uninstall and reinstall.
    Here are the steps to uninstall cleanly.

    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).

    Regards´╝î
