We provide hints and tips to help you get started with the main programs RFEM and RSTAB.
When starting the program, the following error message appears: "CPPSQLITE_ERROR: Error in material library File name: ... Description: Can't find norm group 'EN'"
1. the installed material library "Materials.dbd" with the current Materials, and
2. the user-defined material library "Materials_User.dbd.".
One of the libraries has probably been transferred from another version or computer. In order to solve the problem, you shoul copy the second library as well.
Otherwise a new installation is necessary. In that case, the program including the broken library is uninstalled automatically.
