Why do I get the message when starting RFEM 2D / RSTAB 2D that program authorization has failed?


After installing RFEM 5 / RSTAB 8, there are three program links from each program family on the desktop. These are the links to the 3D program version, the 2D program version and a license-free viewer version. You have purchased the 3D version of RFEM / RSTAB. The 2D version is not part of your license, so you will receive an error message when starting this version. Please start the 3D program link of RFEM / RSTAB here. In the 3D version of RFEM / RSTAB you also have the possibility to generate 1D / 2D structures.
