When starting RFEM 2D / RSTAB 2D, why do I receive the message "Program authorization failed?"


After installing RFEM 5 / RSTAB 8, three program shortcuts of each program family are available on the desktop. These are the shortcuts to the 3D program version, the 2D program version, and a license-free viewer version. You have acquired the 3D-version of RFEM / RSTAB. The 2D version is not part of your license so that you receive the corresponding error message when starting this version. Please start the 3D program shortcut of RFEM / RSTAB here. In the 3D version of RFEM / RSTAB, you can also generate 1D / 2D structures.
