I'm having trouble getting Fallout London to install. It's giving me a permissions error. Running as admin doesn't help. I went into security properties on both folders and made sure users were set to Full control and restarted Galaxy. Still won't install. I even deleted Fallout 4 and redownloaded it. Any ideas?

OK, I fixed it. I hit Change Folder on the install screen and pointed it at the same Fallout 4 folder it was already using. For some reason it's working now. I have no idea why.
