Hi Rudolf,
This is an issue we're experiencing with very select users. It's currently being investigated, but we believe it may be related to a shortage of system resources during the installation process when injecting the personal edition license into the application. Nothing has been confirmed as of yet, but if you can share your setupengine.log files, we can take a further look.
It should be located in your C:\Program Files\SAP Lumira\InstallData\logs folder.
If you can send it to support.lumira@sap.com, it would be greatly appreciated.
Best regards,
K
