You can install a service pack to update a Tekla Structures version or a previous service pack. Service packs can contain new features, and improvements and fixes to existing features.

1. Install the Tekla Structures service pack software.
   1. Download the service pack software installation file from Tekla Downloads to your computer.
   2. Double-click the installation file to run the installation.
      
   3. Follow the steps in the installation wizard to complete the installation.
      

      Note that if you have the related Tekla Structures version or a previous service pack already installed, you cannot select the installation folder. The service pack will be installed to the same folder as the version that you are updating.

      If you do not have the related Tekla Structures version or a previous service pack installed, you can select the installation folder and the model folder.

2. Install the Tekla Structures environments.

   Note that the location of the environment installation folder depends on where you have installed the software. You cannot select the environment installation folder in the installation wizard.

   You do not need to remove any environments. Installing a newer version of an environment automatically upgrades the older version of that environment.

   1. Download the needed environment installation files from Tekla Downloads to your computer.
   2. Double-click the installation file to run the installation.
      
   3. Follow the steps in the installation wizard to complete the installation.
      The environment setting files are installed to the environment folder when you start Tekla Structures after the installation. Tekla Structures opens a dialog box that shows the installation progress.
