The Czech user interface for ATENA Engineering can now be selected in the installer, i.e., no separate _CSY installer is needed any more.

Although we have not prepared a special DEMO installation from version 5.7, it is possible to install the current version and use it without a key in DEMO mode (compared to the special DEMO installation, you need to click the message about switching to DEMO every time). If you are primarily interested in features not available in the standard DEMO version 5.3.5, we recommend to install the current version 5.7 without a license to try it.
