Answer:
The first option is to reinstall the program. The first time you try to reinstall the program, you will be asked if you want to start deinstallation first. Confirm the query and reinstall the program.The second option is to manually integrate the existing material libraries of another computer on which the programs are already installed. Thus, the following material databases must be synchronized in each program version:
- Material library "Materials.dbd" installed by the program together with common materials
- User-defined material library "Materials_Purpose.dbd"
By default, these databases are located in the hidden folder C:\ProgramData\Dlubal\RFEM\General Data
Also, you can find the material databases for versions RFEM 5.18 and RSTAB 8.18 in the download links.
