Lighting build failed. Swarm failed to kick off

Hi Tim, I am using 4.9. I moved whole project to the backup server where I am only storing projects and resources. I don’t have UE4 installed there, because it is just storage. So when I move project back to my computer where I work and build my projects I get message that swarm agent failed to kick off. I seams that it corrupts my projects after I move them…
