If you have your own SQL Server and wish to use this, you can skip directly to the Consignor Server installation.
Download and run the file as administrator: SetupSRV.exe
During the installation, you do not have to do any changes until the "Create Database" step. A new window will open up at this point. (See screenshot below). Here you need to change the Database Server Name if the SQL Server has its own instance, just name it like this: Servername\Instance.
The Consignor Server installation needs an SQL user with sysadmin rights. Create a new user with these rights or fill in the login information to the existing 'sa' user.
If this is a fresh install, you will be asked for an installation key from startup - this should have been sent to you by e-mail from Consignor Customer service.
If you are moving Consignor, you can continue from step 4 in this article about moving Consignor.
