FAQ 000070 EN


I have installed RFEM/RSTAB properly without any error messages. When opening the program, it does not start as a full version but shows a dialog box where the authorization file can be imported or the test license can be started. The dongle is red and so the hardlock should be ok. What can I do?


This is probably caused by the installation that was carried out without administrator rights or without the current authorization file. In the first case, it is necessary to approve the write access for the respective user regarding the file folders of the Dlubal Software programs in Windows Explorer, and to import your authorization file again.

In the second case, you only need to visit the extranet of the Dlubal Software homepage and download the current authorization file after entering your user data. Then, this file can be reimported as well after opening the respective Dlubal Software program.
