How to install a DMB database file  (Annual, Classic, Deluxe, Greatest Players/Teams)

When you buy an Annual Season, Classic Past Season, Deluxe Past Season, Projection Season, All-Time Greatest Teams, All-Time Greatest Players or All-Star Teams database from Diamond Mind, you can use the Install Database command from within the Diamond Mind Baseball version 12 game to load your new database into the game.

If you are looking for help for other Diamond Mind software please see the DMB Knowledge Base for more tutorials.

Downloading your file:

When you make a purchase from the Diamond Mind website, you are sent an email with the subject "Your Diamond Mind Baseball downloads are ready". This email should arrive within about 30 minutes. The links to download your files can be found in that email.

Once you have received your downloads email, you can either click the links or copy and paste the URLs into your browser to open the download page for each item.

From the download page, click the "Download Now" button. Depending on your browser settings, the browser should either start the download immediately or ask where you would like to save the file. If prompted, choose where to save your file on your computer. The usual location for files saved from the Internet is the Downloads folder.

Important: Season database files must be installed from within the version 12 game as described below. DO NOT try to open or run the file directly from your web browser.


Installing your database:

The Install database command takes care of creating a folder on your hard drive, extracting the files, and adding the new database to the list of databases that you can use with the Diamond Mind Baseball version 12 game.

All Diamond Mind database files are delivered as compressed files with the ".alt" file name extension (for example, sd2020_v12.alt).

1Start by opening the Diamond Mind Baseball version 12 game. Then, click File on the game's main menu bar and select Install database (or Install season disk in earlier versions).

A window similar to the following will appear.

Open dialog

2Click on the Look in dropdown box near the top of the window to select the folder location where you downloaded and saved the database installation file.  For example, the Downloads folder.

If you are installing a database from another location, such as a backup drive or CD/DVD, you would select that location instead.

Navigate open dialog

 Locate and select the database file that you wish to install.  For example sd2020_60gms_v12.alt.

Select database

4. Click the Open button to begin installing the season. 

The DMB License Agreement appears first. After you read and accept it, the Create new database window will appear.

Name of new database window

In the Location for the new database box, enter the folder location where you want to store the installed season database. DMB assumes that you will wish to create the folder for this season database within the main game folder (C:\dmb12), but you can choose any location on your hard drive or network by clicking on the ellipsis button to the right.

In the Name of the new database box, enter a name for the new season database or accept the name suggested by DMB.

Note: The location for the new database will be filled in for you. By default, the location will be the DMB installation folder. This is generally where all your databases will be saved, so there's no need to change this.

5Click the OK button to continue. The installation progress will be displayed.

6. If this season file is not already in the current version format, you will be asked whether you wish to convert it to the new format.

7When the installation is complete, the newly-created database will be the active database.  Click the OK button to complete the installation.


When you have multiple databases installed, you can use the Change active database command from the File menu to switch between them.  The current active database will always be displayed in the game's title bar.

Final Note:

To protect your investment and to avoid replacement fees, it is important to maintain a reliable backup of your DMB files. No registration or activation code is required to use any Diamond Mind software and there is no limit on the number of times you can use your original files to install the game or any of your seasons on multiple computers for your personal use. This allows you to easily make backups of all your DMB software and copy your files between computers using many different methods including a portable hard drive, USB drive, or an online file storage service.
