AnswerMake sure that there is no planned installation currently in progress. In Task Manager, this can be displayed as an active app and as a background process called "Windows Installer."If Windows Installer is still displayed in Task Manager after restarting the computer, it can be selected and closed by clicking the "End Task" button.Then, you can carry out the desired installation.
AnswerThe capacity of your C: drive does not allow the installation of the program. You should choose another partition of your hard drive for the installation. You can proceed as follows:
- Start by displaying the "Run" command from the Start menu by clicking Start → Run (or Windows + R).
- Type regedit and confirm.
- Open the key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
- On the right, double-click the ProgramFilesDir key and modify the data of this key by entering a new path of the installation folder.
- For example, enter the path D:\Program Files to change the partition on which the installation will take place.
- Finally, restart the installation by double-clicking the icon.
AnswerYes, the problem might also be caused by RFEM. The preview of RFEM files in Windows Explorer may cause Explorer to react more slowly.For a possible solution, proceed as follows:In C:\Program Files\Common Files\Dlubal, rename the ThmShellEx64.dll file to BACKUP-ThmShellEx64.dll.
In the case of the 32-bit version, rename the ThmShellEx.dll file in C:\Program Files (x86)\Common Files\Dlubal to BACKUP-ThmShellEx.dll.
Finally, it is necessary to restart your PC.
To do this, open the "System Diagnoses" option in the "Help" menu and click the "Send Email" button.Figure 01 - System DiagnosticsThis feature prepares an e-mail with your system, register, and authorization information.
AnswerThis is a bug that occurred in the version 5.10. In the current versions, it has been fixed. The error was caused by a Windows update that set automatic deletion of temporary files and folders. The program has created a folder to store temporary files or calculated results. Unfortunately, Windows deleted the folder before finishing the calculation. The program had nowhere to store the data and displayed the message: "Write Data() failed of module RF‑STEEL EC3." Unfortunately, the data cannot be restored. To resolve this issue, deactivate the Windows function deleting the unused temporary files or install a newer version of RFEM.
The current versions of RFEM 5, RSTAB 8, SHAPE-THIN 8, etc. are fully executable under Windows 10.
For legacy Dlubal applications, for example, Unfortunately, we can no longer guarantee compatibility with RSTAB 7 and RFEM 4.
AnswerThe dialogs in the Dlubal programs are optimized for the display size in the control panel of 100%. You may be able to correct the problem if the display size in the Control Panel is changed to 100% (see Figure 1) or / and a higher resolution is set.Remedy could also be the deactivation of scaling at high DPI values. To do this, open the properties by right-clicking on the program icon. Under the Compatibility tab, check the box for Overwrite high DPI scaling behavior. Scaling performed by: and select the setting application from the drop-down box. Then accept the change and confirm with OK (see Figure 2).

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.
