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

Q: Why do I get a message that the authorization of the program has failed when starting RFEM 2D?

After installing RFEM 5 or RSTAB 8, you will find three program links of 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 5. The 2D version is not a part of your license, so you will receive a corresponding error message when starting this version. Therefore, please start the 3D program link of RFEM. In the 3D version of RFEM 5 (or RSTAB 8), you can also generate 1D/2D structures.
