To avoid security risks such as viruses or data corruption, it is highly recommended to use official channels:

Presto is natively available in Español (Spanish) as it was developed in Spain.

The version is an older, legacy version of the software. Modern construction firms typically use much newer versions (like Presto 2024 or 2025) to maintain compatibility with current BIM (Building Information Modeling) standards and Windows operating systems.

Official versions are typically installed on a workstation. "Portable" versions (those that run without installation from a USB) are usually unofficial modifications that may contain malware or bugs.
