Copy the backup file, InventoryControl_V73_Blank.bak to the SQL backup folder. For 64-bit versions of Windows, this will be C:\Program Files (x86)\Microsoft SQL Server\MSSQL.1\MSSQL\Backup. For 32-bit Windows, it will be C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Backup.
If you have the Standard or Professional version of InventoryControl, or if you have Enterprise but allowed the installer to install SQL Server 2008 Express, run Restore.bat.
If you have Enterprise, you can restore InventoryControl_V73_Blank.bak in SQL Server Management Studio, but after restoring it, you will need to also run FixInventoryUser.sql.
