Tas Data directory

When Tas is installed, a 'Tas Data' directory containing the required templates and database files will be installed to the active user's documents folder. If a different user wishes to use Tas on the same computer, they will need a copy of this folder. It can be downloaded from the above link.
We recommend this zip file be extracted to the user's documents folder. In Tas Manager, you can set the Tas Data directory path in the main window, and you can set the Templates and Databases paths in the Settings dialog.
