Instead of displaying the results in the STEEL‑EC3 add‑on module, the message "Write Data() failed of module RF‑STEEL EC3" appears. What can I do?


This is a bug that occurred in the version 5.10. In the current versions, it has been fixed. The error was caused by a Windows update that set automatic deletion of temporary files and folders. The program has created a folder to store temporary files or calculated results. Unfortunately, Windows deleted the folder before finishing the calculation. The program had nowhere to store the data and displayed the message: "Write Data() failed of module RF‑STEEL EC3." Unfortunately, the data cannot be restored. To resolve this issue, deactivate the Windows function deleting the unused temporary files or install a newer version of RFEM.
