Unity is instaled on disk D: And by path C:\\buildslave\\unity\\build.... I dont have anything

Answer 1

I have seen a lot of different answers, but in my case, when building to Standalone, it turned out I left the game running from the previous build and it was preventing the new build from creating an executable.

Same 2 errors [0x00242] and [0x0007f]. I just had to close the game...
