SQL Error facing during New Bigfix installation

I am trying to install a new BigFix Server using a local SQL Server database. During the installation, I am encountering the error shown in the attached screenshot.

Could anyone help identify the root cause and suggest a resolution?

Environment Details:

  • BigFix Version: 11.0.6

  • SQL Server Version: SQL standard 2022

  • Database Type: Local SQL Server

  • Operating System: Windows 2022 (21H2)

I have attached the error screenshot for reference.

Check if the user has the sysadmin privileges.

As mentioned

Important:
When installing or upgrading BigFix, the user account performing the installation or upgrade must have sysadmin server role in SQL Server.

When working with a remote instance of SQL Server, the AD domain service account must have dbo rights, that is db_owner on the BFEnterprise and BESReporting databases.

Start with sysadmin server role to perform the installation or upgrade, then back off the privileges to db_owner after the product is up and running.
