Performing a clean install of Tekla Structures


In this article, you will learn how to perform a clean installation of Tekla Structures. You might want to do this if there are compatibility issues with Tekla Structures or if you are experiencing crashing and have already tried the suggestions here: https://teklastructures.support.tekla.com/support-articles/tekla-structures-crashes-freezes-or-does-not-start.

Pre-requisites before starting

1. Save any customizations or add-on files you might have made to local installations.

2. Back up models to secure location before modifying system files.
 

Uninstalling Tekla Structures

On your computer, go to the Windows -button and click on the gear symbol. Then, go to the settings and click the Apps -button. Next, search for "Tekla".

It is important that you uninstall any environments or extensions first. The picture below shows you what type of files you should remove first.

After you have removed all the extensions and environments, you can uninstall the service releases if you have service packs installed. If you have not installed any service packs, you can uninstall the main software installation.

Next, you need to delete any leftover files. You can do this by opening the file explorer app and using it to navigate to your Tekla directory. The location of the Tekla directory varies. The examples below show some typical locations:

C:\TeklaStructures
C:\Program Files\Tekla Structures
C:\ProgramData\Trimble\Tekla Structures
%localappdata%\Trimble\Tekla Structures

Please note that the Tekla Structures version 2019i has folders named 2019.1. For example, C:\Program Files\Tekla Structures\2019.1\ is where you will find files related to 2019i. 


You should delete all files which relate to that version of Tekla Structures you are uninstalling. Deleting those files will help ensure a successful installation of the new version of Tekla Structures.
 

Cleaning the Registry

Warning: Please use caution when editing the registry. Serious problems may occur if you modify the registry incorrectly. These problems might require that you reinstall the operating system. Tekla cannot guarantee that these problems can be solved. Modify the registry at your own risk.


The next step might require help from your IT admin if you are not familiar with the registry or if you do not have access to it.

Open the registry on your computer (Start > Regedit) and delete the version-specific registry keys under the following locations:

1. HKEY_CURRENT_USER\Software\Trimble\Tekla Structures\
2. HKEY_LOCAL_MACHINE\SOFTWARE\Trimble\Tekla Structures\
3. HKEY_LOCAL_MACHINE\SOFTWARE\Trimble\Tekla Structures Environments\

 

After uninstalling Tekla Structures you can re-install the program. To find installation instructions please click here
