Complete failure to install

[NeedsHelppps]

On my Windows 11 PC I download JellyfinMediaPlayer-1.9.1-windows-x64.exe and do a basic install. Immediately I get an "Error opening file for writing" for C:\Program Files\Jellyfin\Server\BDInfo.dll and after that it's about the commandline.dnl and after that if I keep clicking ignore it's a ton more and nothing works. I googled it and tried unblocking the file but can't find that as an option. How do I fix a download where it can't do anything? And why is writing a post on this forum complicated and it keeps changing the font color to matching blank white that doesn't show and I can't copy/paste anything withou ctrl+shift+paste or else it has the same hidden color?

You have some conflicting things going on.  JellyfinMediaPlayer-1.9.1-windows-x64.exe is our desktop CLIENT, but then mention the path for Jellyfin server.  So I'm not entirely sure what you're trying to do or what you have going on.

If this is a fresh install and you have no configs to preserve, uninstall everything Jellyfin related.

Download this for the SERVER.  https://repo.jellyfin.org/releases/serve...ws-x64.exe

Right click the installer and run as admin
Choose a basic install
When prompted near the end, allow jellyfin through Windows Firewall

You can simply use your browser to use Jellyfin, but the desktop client has much better codec support.  Download that here, though you seem to have it already.

I downloaded that server. This happens right as it starts:


What is going on that makes this not work? I just did a factory reset on this PC and a network reset.

file inaccessible

common causes
service is already installed and running
user does not have permission to access the destination
destination does not exist therefor destination is not accessible

potential fixes;
check services to see if jellyfin is running
open the file location in file explorer
check if file exists, if exists attempt to delete; on failure to delete investigate
check file permissions
check location permissions

alternative; install to different location (if not already installed)

I second the idea that Jellyfin is still running.  Make sure there aren't any zombie jellyfin.exe processes in Task Manager.

A zombie jellyfin in Task Manager was the problem, tyvm!

Next, I don't get how to connect the server to my desktop client. It's working in the browser, but for the program to want to Connect to Server, under host, what do I put? It says, 192.xxx.1.1xxx:8xx6 (x's in case that's private) or https://myserver.com, but when I enter them into my browser neither work.

Nevermind, figured it out! Next question - if my goal in Plex was to share my server through remote access, how do you do that on jellyfin? Not quite the same thing as there being a Plex app to download on your Smart TV?

[TheDreadPirate]

Because Plex required you to login with their servers, that also allowed them to do some networking wizardry to have their infrastructure act as a reverse proxy.  Obviously Jellyfin can't do that since the point is to self host everything.

You have two paths.  The simple path and the harder, but right, path.

Simple:

1) Sign up for a free DDNS domain (NoIP or DuckDNS)
2) Install the IP updater app from the DDNS provider on your PC.  This will automatically update your IP address for your DDNS address if/when it changes.
3) Setup port forwarding on your router for port 8096 and direct it to your PC running Jellyfin.

Done

Hard:

1) Do steps 1 and 2 from Simple.
2) Setup port forwarding on your router for port 80 and 443
3) Setup Caddy to act as your reverse proxy.  https://jellyfin.org/docs/general/networking/caddy/
4) Get HTTPS certificates from Let's Encrypt
