I was just about to perform the punching shear design in RF‑PUNCH Pro and assign shear rails of HALFEN for the design. But when I click the [HDB...] button, a warning only appears. What have I done wrong?


Check if the design software Punching Shear Reinforcement HDB from HALFEN has been successfully installed and also registered. The best way to test it is to start the design software HDB without using RF-PUNCH Pro, either from the Windows start menu or from the desktop shortcut.

If starting the program has been successful, you can use the interface of RF-PUNCH Pro to HDB for further processing.
