• ### How can I install the interface to Rhino and Grasshopper?

FAQ 004254 EN-US

Please make sure that Rhino (version 6.20 or later) is already being installed. Then carry out the RFEM 5 installation. For this, you need at least version 5.21.02. The plug-ins are automatically saved in one of the following directories and installed during the installation.

C:\Program Files\Common Files\McNeel\Rhinoceros\6.0\Plug-ins\
C:\Users\#USER#\AppData\Roaming\McNeel\Rhinoceros\6.0\Plug-ins\

After completing the installation, Rhino and Grasshopper can be started. In both programs, the Dlubal-specific toolbars should be available by now. It is possible to attach the Dlubal Toolbar for Rhino to the other toolbars also retroactively (see video).

If Rhino has been installed later than RFEM, the interface is not available. In this case, it is recommended to perform a reinstallation of the RFEM.

• ### There was a notification when installing the program: "An error occurred while trying to create the C:\Users\Public\Documents\Dlubal directory". How to solve it?

New

FAQ 004248 EN-US

You may not be sufficiently authorized to install new programs. Try to right-click on the installation file from the menu, and select ‘Run As Administrator’. If this does not help make sure you have the rights to the folder. You can assign rights using Windows Explorer: Choose a folder and open the appropriate properties. On the Security tab, for example, you can define full access for a user group or a selected user using the Edit button.
• ### Where can I find the install logs or the MSI log files of a program installation?

FAQ 004143 EN-US

The logs or log files of an installation can be found under the following path:

C:\Users\Public\Documents\Dlubal\Logs

• ### During the installation, I get a message from the installation wizard that another installation is in progress right now, and the current installation cannot continue. What can I do?

Make sure that no planned installation is currently performed. In the Task Manager, this can be displayed as an active app and as a background process called 'Windows Installer'.
If a Windows Installer is still displayed in the Task Manager after restarting the computer, it can be selected and closed by clicking the 'End Task' button.
Then, the desired installation can be carried out.
• ### Do you have to install the full version or test on Windows Vista, an alert message indicating you have insufficient free space?If so, how?

FAQ 003471 EN-US

The capacity of your C drive: no longer allows installation of the program. You must choose another partition of your hard drive for installation. You can proceed as described below:
• Start by displaying the "Run" command from the Start menu by clicking Start Menu> Run (or the Windows + R key)
• Type regedit and confirm
• Open the key: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion
• On the right, double click on the key: ProgramFilesDir and modify the data of this key by the 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, you restart the installation with a double-click on the icon.

• ### During the installation, I get the message 'Failed to install hardlock.cat signature'.How can I fix this?

The license drivers are digitally signed. If you try to install a new license driver that is missing in the existing signature of your operating system, a message appears.
To solve this problem, please perform a Windows update. After having restarted the operating system, the installation should be completed.
• ### I would like to install the programs on the drive D:\ instead of C:\. Unfortunately, this is not possible for some program folders. What can I do?

FAQ 003006 EN-US

If the program has already been installed on your computer, the path specification of the folders for general data and projects will be grayed out in the Installation Wizard. Thus, any subsequent change is not allowed anymore.

These paths can only be accessed after you uninstall all Dlubal Software applications and reinstall them again.
• ### Is the cross-section program DICKQ only available as a 32-bit version or is it also available in a 64-bit version?

FAQ 002965 EN-US

The DICKQ program is only available as a 32-bit version. You can also use them on a computer with a 64-bit operating system.
• ### If new versions of RSTAB and RFEM are installed using msiexec, will the old versions be overwritten?

FAQ 002940 EN-US

No, the old versions will not be uninstalled. Thus, several versions of RFEM can be used simultaneously on the computer, which makes sense in many cases.

If you want to uninstall an old RFEM version, you can do so with the following command:

msiexec -x <old MSI package>

For a complete list of all msiexec capabilities, use the following command:

msiexec -h

#### First Steps

We provide hints and tips to help you get started with the main programs RFEM and RSTAB.

#### 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.
