How to uninstall Backup Exec 2012

Hi everyone !

On a Windows 2008 Server R2, vCenter Server (a component of VMware vSphere) has been installed with SQL Server 2008 Express (for vCenter database).

On this same server, I installed later Backup Exec 2012 on a SQL instance created by SQL Server 2008 Express.

Now, I try to uninstall Backup Exec 2012 with Remove/Add program of Windows Server.

After clicking Yes to confirm, the uninstall process shows that it will remove:

1. Backup services (or some thing like that)
2. Backup Live Update
3. Microsoft SQL Express

Could you telle me what happens in this case ?.

The uninstall process will remove SQL Server 2008 Express and all databases (like vCenter) located on it ?

Thanks you for your help.
