Hello, it looks like the NetworkProfiler is absent from latest release (checked on 5.6 & 5.8), but was still present in 5.4, and working with capture from 5.6. The documentation of 5.8 is still talking about it (here: Using the Network Profiler in Unreal Engine | Unreal Engine 5.8 Documentation | Epic Developer Community), so I suppose this is the executable that is somehow missing from latest version ?
