How can I create client logs if I do not have access to the client / client configuration?
You can enable and disable writing Connect Client Logs in the registry. To do this, open the registry editor and navigate to the path
There you will find two keys:
Edit the corresponding keys and set either the value "Verbose" (= enable logging) or "Off" (= disable logging).
The created log files can be found under the path C:\Users\AppData\Local\C4B\Log.
