You can find the installation package and license file by clicking on the customer link you received. Select "Setup Guide".
The installation file should match your registered operating system. Proceed by downloading the package and make sure to also download the license file.
Open the downloaded application. In the first step, you will be prompted to select a language. The installation wizard will then open — accept the license terms to proceed.
You will then be prompted to upload the license file and log in using the same credentials you currently use on your original PC or in the web interface.
In the application, you will see the same companies as before, including all data processed within this instance.
