So far, they have tried reinstalling, we confirmed the permissions on the directory that the browser should be installing to are accurate:

They have also tried disabling XFence / Littlesnitch, clearing their routing table and entirely restarting with the previously mentioned software disabled. There has been no change in the behaviour they are seeing after trying these different things.
