You will have to ask Siemens for the user guide because the software has been acquired by them. When a user visits the official website, the script automatically redirects to the Siemens page. I recommend you do the same and visit the page and contact the developers. They will provide all the necessary information related obtaining the PDF file with the way you can use their application.
On the page you'll find email addresses and contact links. Use the email option first to get in touch.
