Note in advance: Microsoft Defender SmartScreen, antivirus programs and browser security warnings.

During the download and installation, browsers may display various security alerts or ask for confirmations (even after the certifiact is installed). For example, the following notice may come from Microsoft Defender SmartScreen:

In this case, please click on "More information" and then select "Run anyway":

SmartScreen 2

Also when downloading the certificate file, the MS Edge browser may display a warning message requesting confirmation of the download. In this case, please release the download.

Why the warnings can be skipped here: The browser and the operating system warn you that the files could be potentially harmful, because they come from a source that is not known to the system. However, since we offer our files for download exclusively through the XRNAUT  SchoolPortal, you can always be sure that the data actually comes from us, despite the warnings. Please note, however, that we never offer security-related files for download outside of the XRNAUT  SchoolPortal.

Before download (one time)

For security reasons XRNAUT provides all software products with an electronic signature. With the help of this signature the computer can verify if the software was really published by XRNAUT. This verification is done with the help of a "software certificate". Even if this step is not mandatory for the installation, we strongly recommend it.

Installing the software certificate

In the dashboard you will find the button for installing the certificate file.

When you click on it, select (depending on the browser) Open file, or Run/Install certificate. If necessary, confirm a prompt asking if you want to open this file.
After that, please follow the steps below to install the certificate:

This completes the import process and the certificate is permanently stored in the system. The installation procedure must be performed only once for each PC running the simulator.
The software can also be installed and used without a certificate. In this case, several warnings are usually displayed by MS Windows.
