I'm not sure to understand where this screen capture comes from !
Could you attach the last log file from `C:\Program Files (x86)\Orthanc Server\Logs` ?

If you give permission to let the Orthanc service interact with the desktop you can observe this message.
The log file points to the problem: If you create a backup copy of the configuration file "orthanc.json" in the same directory the Orthanc service refuses to start.
Anyway, thanks for your advise !

so what happens if you rename orig_orthanc.json into orig_orthanc.json_ (so it's not loaded).  Do you still have problems ?

When I change the file extension to ".json_" the service starts normally. 
Side note: under Windows it's not good practise to put configuration data in the program files folder. Please consider to move this to suggested places, f.e.: 
C:\ProgramData\<Vendor>\
-> Storage location for application data that is to be shared between all users on that computer.
C:\Users\<username>\AppData\
-> Storage location for per-user application data that is exclusive to a user and should not be shared with any other user on that computer.

noted for the storage location.

Closing the issue since the logs display an error message with the reason of the failure.
