I loaded an Obj file with 9 million polygons and the application crashed upon loading the object,
reduced the polycount to 6 million , then the application crashes when re-topologizing phase

You should provide the obj files so that the developer could reproduce the issue and fix it.
Make sure you was running 64bit version.
