It looks like you're facing a permission issue while installing the demo version of Business Central. The error message indicates that you don’t have the required permissions to create a database on the SQL Server instance 'BCDEMO'.
Run the Installer as Administrator
Check SQL Server Permissions
Manually Create the Database (if the issue persists)
Check for Active SQL Server Services
Disable UAC (User Account Control) Temporarily
If none of these steps work, I recommend checking the installation logs for more details or having an IT admin provide elevated privileges to your user account. Let me know if you need further assistance!
