Installationsfehler bzw. Start nicht möglich

I suggest you do as the message says and contact Elements support. You can start a chat session by clicking on the blue Contact Us button under the Help and Support menu at Adobe.com. Or you can contact Support by telephone using the numbers listed here: https://helpx.adobe.com/contact/phone.html.  Support hours in Europe are limited to the business day.

The problem seems to be a licensing or folder permissions issue.  Support should be able to help you.  Let them know about the 213:5 error.
