Hi Shah the process is:

1. Install required IIS Component for Web Screens (Optional)
2. Install Sage 300 2024
3. Install latest Product Update
4. Configure your Local Security Policy on your SQL server to ensure minimum password age is 0 and password expiry is something more sensible then the default 42 days.  Make sure your minimum password age is 0.  Its likely one of these settings not allowing you to login with 'admin' first time.
   
   (these are my lab server settings, not recommended for production)
5. Create your Sage300Store, Sage300Vault, System, Data and Portal (optional - for web screens) databases.
6. Create a standard SQL Auth account and map db_owner your System, Data and Portal databases to it.
7. Create a Sysadmin SQL Account "Sage300VaultOwner" for the initial configuration of your Sage300Store and Sage300Vault databases.
8. Launch Database Setup and enter 'admin' as the default starter password.
9. Configure your Vault and Store databases using your privileged "Sage300VaultOwner" SQL Auth account.
10. When prompted, change your ADMIN password to something complex.

Good Luck!  Here is the enhanced security guide if you don't have it.  Here is the ADMIN account password change tool in case you get really stuck.
