Backup Exec 21.4 - change SQL version, unable to create SDR iso

Backup exec 21.4 runs on SQL 2014 express 32bit.

Server 2025.

Is there a way to create a new database on SQL express 64bit?

I installed SQL express 2022 64bit but I think the database is still on SQL 2014 express 32bit.

ADK is installed but Backup exec doesn't see it so I am unable to create a SDR iso.

Thanks
