Hi Alex,
Sorry I misunderstood your post, thought I only need the filemgr for the second option (file manager functionality).
However, after some "Error 403: Access denied" messages its working now. The error message directed me to all the access rights stuff, but in the end it was the missing
[filemgr]
RootFolder = C:\
in the agent config file which seems to give the "Error 403...".
Thank you very much Alex!
Bye
