This error can occur during installation on a computer that does not meet the minimum system requirements. Computers running older .NET Framework versions likely do not meet other requirements. To proceed with installation anyway:

1. Download and install .NET Framework 4.6.2: https://www.microsoft.com/en-us/download/details.aspx?id=53344
2. Restart the computer.
3. Re-run the LENA Hub installation. (The installer is most likely still in the computer's Downloads folder. Double-click to install.)
