It just exits. Maybe it's done downloading and not crashing. I can't tell the difference.
It means it has nothing to do, so it quits. In fact, that's exactly what is supposed to happen, considering that with the installer I posted, you surely *do* have the latest version of every file in the Addon Manager folder and, with a further Live Update, it should have downloaded any file that *might* have been updated too, but now included.
However, the Live Update *is* server based so, it's possible, the way servers are acting out these days (we'll reach cloudflare support tomorrow), you might not getting those, so a new full Installer for P3D might still required.
