Can I use RFEM 6 and RSTAB 9 without an Internet connection?

You need a stable Internet connection to log in. Without it, the license cannot be released from the Dlubal server and the software cannot be launched. For temporary periods without an Internet connection, there is a license loan function. This is currently valid for a maximum of 7 days.

The trial period of my trial version has expired. How can I continue to test new Dlubal products?

In the event that you have already successfully completed a test phase, we can only offer a shortened test phase.

If you are interested in a particular add-on, you can always contact one of our sales representatives to allow for individual adjustment of the trial license(s) of the desired products/add-ons.
