Hm.Thank you - this worked fine! Yet - the file 'options.txt' is mentioned nowhere, according to the docs you linked it works with command line options. Maybe the wiki should be updated. Using the link on my desktop (for starting EDDiscovery) I could have also added the command line options - but with the file it works better.
It's stated there:
Options are read from both the EDDiscovery command line and from:
-options.txt if present and located in the same folder as the application install folder of EDDiscovery.exe
-options.txt if present and located in the application data folder (default %LOCALAPPDATA%\EDDiscovery)
