When importing a file (for example DXF) problems arise. A warning appears and the created file is empty. How can I solve this problem?


For a successful import, the main program RSTAB or RFEM must be registered in Windows. The registration can also be done manually in case of problems. To do this, start DLInstaller.exe with RSTAB or RFEM closed and right-click → "Run as Administrator".

By default, this file is located in the following path:
C:\Program Files (x86)\Common Files\Dlubal\DLInstaller

Then, go to the "COM" tab and select the version used (see the figure). To start the registration, click the "Register" button. Now you can test the export/import again.
