I did as you suggested and found that I got a message at 55% of the system scan saying that “Windows Resource Protection could not perform the requested operations”.
However, I have found that by enabling Force No Precomputed Lighting in the World Settings, I no longer have to build lighting. I know this limits me to dynamic lighting, but is it entirely necessary to build static lighting? I’ve never been a fan of baked lighting myself so enabling this option would not be such a terrible thing for me.
