The NDI 6 installer sets NDI_RUNTIME_DIR_V6 (and V5/V4 for back-compat) but does not always add the runtime directory to PATH, so a default DllImport(Processing.NDI.Lib.x64) failed with 0x8007007E (DllNotFoundException) on otherwise correctly installed machines, killing both TeamsISO.exe and TeamsISO.Console at preflight.
Add NdiNativeLibraryResolver, registered from NdiNative's static ctor, that resolves the DLL by trying NDI_RUNTIME_DIR_V6 / V5 / V4 in order, NativeLibrary.Load-ing the file from disk before the runtime falls back to its default search algorithm. Static-ctor registration (rather than [ModuleInitializer]) sidesteps CA2255 under TreatWarningsAsErrors and still guarantees the resolver is in place before the first P/Invoke fires.
