We will always upload the latest version of the TBCB program file as a single ZIP file when we release updates. Of course we will also update the TBCB setup file. Please always have a look at the version numbers. We will change the version number each time when we make changes to the code. You'll find the version number on the lower half of the main screen, and next to each download link on our web site.

The changes which were made to the program in a patch, are published on the message board.

To install a patch, you don't need to unlicense the software, and you don't need to uninstall anything. We always suggest to make a backup of the data, i.e. of your databases, before installing a new version or a patch. You'll find the databases in the TBCB program folder, sub directory /data. The name of the datebase which you're currently using can also be found on the TBCB mainscreen. The names of the databases which are available on your computer can be found in the drop-down list "Databases" on the Game Options screen.

To install a program patch, just download the latest patch, and install it into the TBCB program folder. That's all. When you start TB the first time after installing the patch, some updates will probably be made to your database, depending on the version.

To get a full update, it's always the easiest to download and install the full setup file. Again, no need to unlicense or uninstall the software. Making a backup of your database is recommended, but not necessary.
When you install a full setup in your TBCB program folder, your databases will not be overwritten. Only the files in the folder /data/default will be replaced with the new one. This is the default database, which will never be used directly during playing. TBCB uses this default database only when it creates a new user database. This happens when you start TBCB the first time after the initial installation. The user database is usally /data/myDB.
