AnswerAs already mentioned in this message, the corresponding permissions to delete the files are missing or the files are in use.To avoid this problem, the "Sentinel LDK License Manager" service should be stopped first.Then, it is necessary to delete the files "hasplms.exe" and "hasplmv.exe" from the directory C:\Windows\System32.Note 1: On some computers, the files are not located under C:\Windows\System32, but under C:\Program Files (x86)\Common Files\Aladdin Shared\HASP\.Note 2: In some cases, it may happen that the files cannot be deleted. In this case, you have to move the files to the desktop, for example, and then delete them.
Please check the Windows fonts on your PC and check if the "Symbol Standard" font is installed. This is required to display the symbols correctly.
Except for RWIND Simulation, all Dlubal Software products use the same dongle driver. Therefore, the one-time update or installation is sufficient, for example.
AnswerDlubal Software has a modular structure. You can compile the software as required. For this, you always need a main program. It is either RSTAB for frame & beam structures, or RFEM for general finite element calculations (beam structures, surfaces, and solid elements). For this, you can configure the required add-on modules depending on your task.
We can give you general recommendations as to which program combination is possible, but it is better to take some time and select the add-on modules according to the specific needs. The add-on modules that are not required can be simply omitted or quickly reordered if necessary. Therefore, you can only buy the product service that you really need. The programs are also available for purchase without any running costs - an advantage in the eyes of many users.
We will be happy to advise you in detail and without obligation. A first step is often to familiarize yourself with the trial version or watch some short videos. You can send us a short e-mail or give a phone call and we will show you where to find what.
If you want to take a look around, you can find the individual solution-related product combinations on our website.In order to get an idea of the price, the webshop provides you with a wide range of package composition options, including online ordering and payment. Before the final order, you always have the option to download the product compilation as a non-binding offer. The short video attached shows you how to do it.
According to EN 1991‑1‑3, the snow load must be multiplied by the factor of 0.8 for the snow load on a roof. Therefore, the following load results:
sk = 5 kN/m² × 0.8 = 4 kN/m²
If the load has already been calculated for the roof, you can enter the load completely under the user-defined loads. This is shown in Figure 01 and in the video.
AnswerYou can download the previous program versions under the menu item "Support & Learning" on the Dlubal Software website (see the figure). The direct link is below this FAQ.
AnswerIn RX‑TIMBER, you can create a user-defined material as a new material in the material library (see the figure), similar to the programs RFEM/RSTAB.In contrast to RFEM/RSTAB, the category is set to "timber" in this case.
AnswerIf using a real computer with the Windows operating system and there were no hardware changes and/or new installation of the operating system, the license problem is usually caused by the following:
- The mandatory service "Sentinel LDK License Manager" may be damaged after a Windows update.
- The antivirus program blocks the hasplms.exe file.
- Other security software (for example, Sandboxie) prevents proper communication of the license service.
AnswerTo recognize the background of your license issue, we need the diagnostics file. You can create the file by using the menu Help → Authorization → Diagnostics (see Figure 01). For this, simply run the program in the demo version.In RX‑TIMBER, you can create this file by using the menu Help → System Diagnostics (see Figure 02).
AnswerIf this error occurs, the download did not run correctly. Please download the program again. Please note that the file can only be opened after the complete download.

Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
“Thank you for the valuable information.
I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. I have used a lot of software with a support contract in the field of structural analysis, but your support is by far the best. ”
