Licensing & Authorisation RFEM RSTAB 5.xx 8.xx

Why do I suddenly receive a warning "Program authorization failed"? Yesterday, I could still open RFEM/RSTAB as full version. I am not aware of anything changed.

Answer

Please check, if RFEM/RSTAB has been accidentally opened by clicking the 2D version shortcut. 2D versions have a different license key. However, all shortcuts are created automatically during the installation.
