Hello, i'm trying to import a settings zip file in VC via the API but the call return false as a result. I'm using version 8.4.1 in trial mode and the TestClient project from the API\sample folder. I have changed the path in the btnImportSettings_Click event to point to my settings file, the client connects successfully to the server but the call returns false. I have enabled debug logging in the settings and the output in the log file is the following:

Importing the same file through the UI client works fine. Can you help me with this issue.
