Tekla Structures crashing, freezing or not starting can have several causes. The following checklist may help determine what is causing an error message in Tekla Structures. Go through and review the following steps and take any necessary action to avoid crashes.

(Click here for the checklist. You can send this list to your local support team to report an error message).

  Checklist Yes No
1 Which operating system are you using? 
Windows 10 or Windows 8.1 = Yes
Windows 7 = No.
(Tekla Structures 2017i is compatible with Windows 10, Windows 8.1/8 and Windows 7 SP1.
Tekla Structures 2018, 2018i, 2019, 2019i and 2020 are compatible with Windows 10 and Windows 8.1).
2 The latest Service Pack for your Tekla Structures version is installed?    
3 Are the required C ++ and .NET packages for the respective Tekla Structures version installed on your PC?
See which Microsoft Visual C++ Redistributables and .NET Framework packages are needed for the version of Tekla Structures. This information is available in version-specific Hardware recommendations.
4 Is the error related to your computer's performance? Check the Hardware recommendations for Tekla Structures.    
5 Have you checked that the drivers (graphics card driver, etc.) are updated? Do this even if it is a brand-new laptop or PC, since the factory installed drivers may be old.
Click here for Nvidia and here for Radeon drivers.
6 Have you checked that the Windows operating system is up to date, having the latest Windows updates and drivers?    
7 Is there antivirus programs that could be stopping Tekla Structures from running? Check their settings.    
8 Have you checked if there is any malware installed on your PC? If necessary search the internet, check or scan your PC.    
9 Is only the Tekla Structures version crashing you are currently working in (=Yes) or are also other Tekla Structures versions crashing on you pc (=No)?    
10 Have you already restarted the PC?    
11 Have you already restarted Tekla Structures?    
12 Have you re-installed Tekla Structures?    
13 Is the model opened in a Tekla Structures version that is the same as the Tekla Structures version in which the model was originally started? We strongly recommend that models are finished in the version in which the model was started.    
14 Has the error occurred since other software was installed (recently) on the PC?    
15 Does the error occur since content from Tekla Warehouse has been added to Tekla Structures? Delete this content and check if the error message does not appear anymore.    
16 Is other hardware being used? Zooming and panning with a Logitech mouse in combination with SetPoint software, for example, can lead to a crash. A message about a Crash when zooming: System.OverflowException: Arithmetic operation resulted in an overflow.    
17 Does the error message occur since a certain Service Pack was installed?    
18 Do you work in a large Tekla Structures model? Please check this article about Tips for large model in Tekla Structures.    
19 Are you working in a single-user model? If you are working in a multi-user model, please check the chapter Remove inconsistencies from a multi-user database.    
20 Are you working in a Tekla Model Sharing model? Check the prerequisites for Tekla Model Sharing.    
21 Does the error occur in a specific Tekla Structures model (=Yes) or in all models (=No)?    
22 If the error occurs in a specific model, does the error also occur when another Tekla Structures user opens the model on his PC?
If the error occurs in a specific model, check and repair the model (in single-user mode). To do this, go to File > Diagnose & repair> Repair Model.
23 Is the model created on the basis of a model template? Do models that are made without or on the basis of another model template not crash? Check the original model template and update the model template to the Tekla Structures version you are working in.    

Silent crash (without error message)

Is there a "silent" crash, so without an error message, or a crash when starting Tekla Structures? Tekla Structures may crash "silently" when you double-click the Tekla Structures startup icon. Nothing happens and Tekla Structures is not being started. This can be caused by missing C ++ and .NET packages, see point 2. Crashing Tekla Structures when starting can also be caused by a crash of the file Kernelbase.dll or by other so-called hooking software. You can also check the article Tekla Structures does not start.

When Tekla Structures crashes without an error message, check the error message in the Event Viewer in Windows:

- Click Start 
and type "event".
- Click Event Viewer, dialog box Event Viewer appears.
- Go to Windows Logs and next Application:


- In the Level column, check for an Error.
- Click the line  to check all detailed information about the error in the tabs General and Details, you should see a view similar to the image below:


In this case, the error is related to the file KernelBase.dll, click here for more detailed information.

If an error message does appear, check in Tekla User Assistance or check the Internet to see if it is a known error message by searching for the message (or part of it), for example the exception code or the name of the *. dll file.

Send an error message to the Construsoft Helpdesk

It is important that you provide us as much information as possible regarding the steps mentioned above that you have taken. To send an error message to the Construsoft Helpdesk, you do next:

1. In the Event Viewer, select the line(s) of the error message and click right mouse button.
2. Select the option Save selected Events... to save the error message(s):


3. If possible, open the Tekla Structures model and double-click macro CS_Save_Catalogs in the Applications & components database. This macro saves the material- (matdb.bin), bolt- (screwdb.bin) and bolt assembly catalogs (assdb.bin) in the model folder so that the Construsoft Helpdesk has the correct databases belonging to the model.

4. Contact the Construsoft Helpdesk and (if possible) include the following information:
   a. The saved *.evtx file (Event Viewer).
   b. The checklist completed by you (*.doc file).
   c. The entire model folder of the concerned model (this also gives Construsoft all *.log files that are stored in the model folder).
   d. A clearly legible screenshot of the error message.
   e. The steps you take that caused the crash.

Create and forward a crash dump file

Sometimes when Tekla Structures crashes there is not enough information available on what exactly is the reason for the crash to come to a solution. In those cases, you can send a so-called "crash dump file" to the Construsoft Helpdesk to investigate the concerned model. Click here for a step plan to create and forward a "crash dump file".
