MicroStation Connect deployment

I've created a deployment of MicroStation Connect 10.13 which is set up with a passive (non-interactive) UI. It installs as expected when manually double-clicking the exe. However when this same exe is executed via PDQ Deploy, it apparently stalls out as if it was running the install wizard in interactive mode, so the deployment installation never finishes. What is causing this problem and how do I work around it? The folder on the server is a UNC path, if that matters.
