Installation RFEM RSTAB

The authorization fails when starting the program. It seems that the dongle is defect. What can I do?


Information about the dongle test: using the following link, you can download a program that you can use to write the data of the hardlock (dongle) or network dongle plugged in the computer into a file:


First of all, unpack the file KeyDump_HASP4.zip and execute the file KeyDump.exe in the unpacked folder. Then, a small tool opens where you see the hardlock displayed below License Information.

If it is not displayed, the dongle is maybe defect, or the driver is not installed correctly. Usually, dongle drivers are installed automatically together with the installation of RFEM or RSTAB. But if this is not the case, a subsequent manual installation of the dongle driver may solve the problem. Use the following link to download the current driver from the producers for the respective operating system:


Furthermore, you should check if only the Dlubal Software hardlock is plugged in the USB port during the installation. Remove dongles of other producers, if necessary.

The successful installation under Windows requires administrator rights.
