I’m getting - this error. “The feature you are trying to use is on a network rescource that is not available” set path to find pms-shutdown.msi.
I found the file and the path but plex is saying the file is bad or damaged.
I fixed the problem. Went into my plex updates directory and found a previous install that allowed for a repair or uninstall. I ran the repair and after it completed successfully, I ran the latest update.
