Getting started with Nightly Builds

This version is abandoned; the code base was completely reworked into a new version called Reborn. As such, the Nightly Builds won't receive any further updates, but you can still play on them until Reborn has caught up to (and replaced) Nightly Builds.
Overview
Nightly builds are builds (versions) of a software that are untested and automatically built every time there is an update on the main branch. Now that Skyrim Together's Nightly Builds have been deprecated in favor of Tilted Online, they will no longer receive any updates. However, the last Nightly Build is still more playable than Tilted Online is in it's current state, so this guide serves as an explanation for getting started with the Nightly Builds.
This guide will go over the installation, setup, and most common problems players have encountered during installation and the use of the Skyrim Together Nightly Builds.
This guide is meant for installation and use of Skyrim Together on Windows 10. Although it should work on older versions, e.g. Windows 7, you may run into issues.
Guides
While we have multiple guides in-place for different actions. We recommend everyone who wants to play Skyrim Together to follow these following guides for the best player experience.
How to Download and Install Harbor and Skyrim Together
Supported Games - Nightly Builds
Step 1.
Acquire the Harbor installer, by going to the following github page and download Harbor-X.X.X.exe Harbor is the launcher for Skyrim Together.
Step 2.
You may choose to Run it without saving or save then run, for this tutorial we will be saving it and then running it.

Click 'Save As' or 'Save' when the option appears and depending on the browser it will either automatically download to your Downloads Folder or ask you where to download it.
Step 3.
For this version of Microsoft Edge it automatically downloaded to the Downloads folder, this folder can be accessed by going to 'Downloads' in Windows Explorer.
Step 4.
After navigating to your 'Downloads' folder, you will be greeted with the Harbor application.
You can now run it by double clicking or by right clicking and selecting 'Run' from the menu that appears.
Step 5.
Depending on your computer you may be greeted with the following Pop-up, click Yes to allow Harbor to install.
Step 6.
You will now be greeted with the Install folder window, here you can select where you want to install Harbor.
For the purpose of this tutorial, it will be installed to the default location.
C:\Program File\(x86)\Tilted Phoques\Harbor
Step 7.
Harbor will now be installed to the folder listed previously, if you run into an issue during the below screen, such as Access Denied. Have a look at the 'How to run as Administrator' guide.
Step 8.
Harbor has now been installed and if you leave 'Run Harbor' checked when you click finish it will now run Harbor.
Step 9.
Like before, if you get the window asking if you want to allow this app, click Yes to allow it.
Step 10.
With Harbor now opened you may have 'GAME NOT FOUND' written in the bottom corner, this means that you will have to manually locate your Skyrim install.

On the left side of the 'GAME NOT FOUND' or 'INSTALL' button there is a small box that says 'GAME VERSION' to change between different game versions, click this box and pick the one matching the version you have.
(Check the 'How to find Skyrim Location' guide if you need extra help.)
If you have 'INSTALL' there instead, you can skip to step 17.
Step 11.
Steps 11 through 16 will show you each step in telling Harbor where your game is, using the default game install location of steam.
C:\Program Files (x86)\Steam\steamapps\common\
To tell Harbor where your game is located, click the small magnifying glass on the right side of the 'GAME NOT FOUND' button. Then on the left hand bar, click 'This PC'
Step 12.
Go into your C:\ drive and select Program Files (x86)
Step 13.
Once in Program Files (x86) Go into your Steam folder.
Step 14.
Inside your Steam folder you will likely have other folders and files, the one you need to navigate to is called steamapps
Step 15.
Once in Steamapps click common to get to your games, you may have other folders and files but they are not important for this.
Step 16.
Find your Skyrim Special Edition folder and select it.
Then click 'Select Folder' on the bottom of the window.
Step 17.
You are now ready to install Skyrim Together onto your game. Simply click Install.
Step 18.
Once you have clicked install the button text will change to 'Integrity Check' It will do this every time you load Harbor, before allowing you to update or play.
Step 19.
Once the Integrity has been checked, Harbor will then begin updating, downloading and installing Skyrim Together, this may take some time.
If it stays on '0B' You may need to follow the guides for Windows Defender, Firewall and Ransomware Exceptions. If it still doesn’t work then try the 0B @ 0B/S fix.
Step 20.
Once Harbor has finished 'Updating' it will now allow you to play, simply click Play.
If nothing happens when you click 'PLAY' you may have to run as Admin or add various exceptions for it in Windows, see the below guides for how to do this.

If you are missing  libcrypto-1_1-x64.dll for the server, download this to your Skyrim Special Edition folder

How to run a server
Note: To host a server, you will probably need a way for people outside your own network to connect to you. This means either port forwarding or making use of a program that simulates a virtual LAN. (ie. Hamachi) You don’t have to port forward or use a program like Hamachi if you’re playing with another person on the same network.  

For anybody hosting (dedicated) servers
You can only use the server for personal use, you may NOT sell the server or services designed around this application.

THE SOFTWARE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.
Another option is to make use of the free community provided server hosting service playtogether.gg 
Playtogether.gg
A few of our community members host a free service that provides free private servers to play Skyrim Together on with your friends. If you want to try it out, head to https://playtogether.gg (Playtogether.gg is not affiliated with Skyrim Together).

Port forwarding
Since port forwarding is different for everybody, there’s just no straight-up guide to do it. However, we have made a video on it and this may help you a little.

Portforward.com has some good information about getting started with port forwarding and what port forwarding is. The guides can be found right here. (under the section, Port Forwarding Tutorials)
We are not affiliated with portforward.com, they just have good guides on port forwarding/networking.

We recommend first setting a static ip, this will have the advantage that your IP address won’t change. So you won’t have problems when your IP address suddenly changes. portforward.com has a good guide for this here.

For the port forwarding you’ll need access to your router's login page. The login information for this can probably be found on a sticker on the back of the router that you’re connected to. There’s also a list of default passwords that can be found here.

To get started port forwarding, follow the guide of your specific router model here. The model of your router is also most likely to be found on the sticker which is on the back or bottom of the router.

The port information that you will need to port forward is the following:
Port: 10578
Protocol: UDP
If you have done everything correctly, then your friends should be able to connect to your server, when it is running, using your public IPv4 address, which can be found here.
Virtual LAN programs (ie. Hamachi)
Install the Virtual LAN program, and create or join the virtual LAN. When you’re in the same network as your friend you will only need to use the IPv4 address of yourself. Yourself can connect to 127.0.0.1 (localhost) and your friends can use the IPv4 address of your computer in the Virtual LAN programs network.
Step 1.
To start running a server you will need to navigate to your Skyrim folder, the location of which can be found in the 'How to find the location of Skyrim (Steam)' guide. If you already have the location, you can skip to Step 11.
Open the 'Start Menu' by clicking the Start button on the Task Bar along the edge of the screen.


Step 2.
With the Start Menu open, move your mouse up the left side of the menu and select 'Documents', the icon that looks like a piece of paper with one corner folded.
Step 3.
Once 'Documents' has been clicked it should open a window showing you your documents folder, on the side of this window select 'This PC'


Step 4.
From 'This PC' select your C:\ Drive.
This guide will follow the default install location for Steam and Skyrim, to find your install location, follow the 'How to find the location of Skyrim (Steam)' guide.
​
Step 5.
Then go into your 'Program Files (x86)' folder.


Step 6.
Then open your 'Steam' folder.
Step 7.
Go into your 'steamapps' folder.


Step 8.
Then open the 'common' folder.
​
Step 9.
Inside the folder, select your Skyrim Special Edition folder.


Step 10.
Inside your Skyrim Special Edition directory or folder, open your 'server' folder.
Step 11.
Once inside the folder you will see a file called 'server' or 'server.exe' Open it or run it, by double clicking on it or right-clicking and selecting 'Open'


Step 12.
A window labeled 'Windows Security Alert' may appear after running 'server' to allow it access, select your network and 'Allow access'
Normally your network will be set to 'Private' if at home, you can select both 'Private' and 'Public' if necessary. This window may not appear if you follow the Firewall guide.
NOTE:Do not click on the black window, as this may cause the server to stop working, pressing the 'ENTER' key or re-opening the server will fix this.
​
How to customize your server
Step 1.
Navigate to your server folder, located in your Skyrim installation, which can be found by following the 'How to find the location of Skyrim (Steam)' guide, and keep the window open in the background.


Step 2.
Next, open your Start Menu' and select the Start Button on the taskbar at the edge of the screen and then scroll down to 'Windows Accessories'.
Once inside the folder, open 'notepad' by clicking on it.
​
Step 3.
A blank window shall now appear, that will allow you to type into it.


Step 4.
Type `start server.exe` into it. This will make the server start when the file is created. This is the only entry that is required to start the server.
​
Step 5.
Adding '-premium' will increase the tickrate of the server. This increases how often the server updates changes within the game, which should allow smoother gameplay if possible.


Step 6.
Adding '-port 10578' will change the port the server uses to allow other players to join, this is the port you will enter when 'Port Forwarding' Without adding '-port' the default is 10578, changing this is not required.
​
Step 7.
Adding '-name "NAME"' to the text line, will cause your server to appear on the Public server list in-game with the name you enter inside the "".
NOTE: This can not be used with '-token' and will cause the server not to start.


Step 8.
Adding '-token TOKEN' to the text line, will add a password to your server, this way even people with the server IP address can not join unless they know the token. NOTE: This can not be used with '-name "NAME"' and will cause the server not to start.
​
Step 9.
Once you have selected what you wish to enter, click 'File' in the corner of the window, and select 'Save As...'


Step 10.
Once you have clicked 'Save As...' a new window will appear and allow you to save the Document.
On the bottom of the window, select the box labeled 'Save as type' and change it to 'All Files'
​
Step 11.
Name the file 'run.bat' and click 'Save' It can be saved directly into your server folder, however it is unable to, save it somewhere you can and move it once saved, which is what Steps 12 to 17 will cover.
NOTE: It has to be saved as a .bat file.
Step 12.
If you have been unable to save directly into the folder, you will have to copy and paste the file, to do this Right-click the 'run.bat' file
​
Step 13.
From the right-click menu, click 'copy'


Step 14.
With the file copied, navigate to your server folder and right-click on an empty space.
​
Step 15.
In the right click menu, select 'Paste' and the file will be copied into the folder.


Step 16.
In some cases, a window labeled 'Destination Folder Access Denied' will appear, if this happens select 'Continue' You may also have to select 'Allow' or 'Yes' on a pop-up if one appears.
​
Step 17.
You should now have the 'run.bat' file in your server folder, ready to use.


Step 18.
Double click or right-click and 'Open' the 'run.bat' file.
​
Step 19.
The server will now start and you will be able to see your 'token' on the first line if you have previously set one.
NOTE:Do not click on the black window, as this may cause the server to stop working, pressing the 'ENTER' key or re-opening the server will fix this.

Known problems & fixes
On top of the fixes listed here, we also have a list of fixes here.
Problems
Missing libcrypto file
If you are missing  libcrypto-1_1-x64.dll for the server, download this to the location of server.exe.

​https://cdn.discordapp.com/attachments/247838017002143746/775133629163634708/libcrypto-1_1-x64.dll 
Can not join server / can not see any servers in the server browser
If you get an error like “connection failed due to an error” or you can’t see any servers in the server browser. Then it can have multiple causes. It’s either the wrong IP address, the current stability of the Network Library or a Firewall issue.

If you’re connecting directly by filling in an IP address, then make sure you’re using the right public IP address. If they have port forwarded, then you will need their public ip address of the person hosting the server. The public IP address can be found here. 

This is not needed when you are making use of a Virtual LAN program (ie. Hamachi) or when you are playing on the same network (local).

The person hosting the server on the same computer as he’s playing on should be able to connect to the server using localhost (127.0.0.1).

If there is still an issue, then it is most likely the firewall blocking the connection. The fix for this issue can be found here.

If that still doesn’t work, then the port forward rule has probably been set up wrong. Make sure you’ve filled in the right information, the Public IP Address of the person hosting the server and the right port. If it still doesn't work, then it is potentially a problem related to your Router’s Firewall settings or internet connection.

Another possibility is that the server you are trying to connect to is running on an outdated server version. The server host should manually delete the server and update it.
JavaScript error when trying to run Harbor
The JavaScript error while trying to run Harbor is caused by an antivirus program blocking the program from running. We have the following fix for this issue here and here.
Crash when you see / load other players
This is either a problem of a corrupt save or a situation where the crossplay ability creates the crash. (crossplay is playing with two players, playing different versions of skyrim; Skyrim Special Edition and Skyrim). Crossplay with oldrim is known to cause issues.

Try loading an earlier save or a fresh save. If that doesn’t fix it. It could potentially be another player causing the crash with their corrupted save. It could also be a bug causing the crash or as mentioned a bug related to crossplay.
Missing UI / no chat box
This could be either your anti-virus deleting/blocking it. Or some files that are corrupted.
First try adding the exceptions in your antivirus, how to do that can be found here and here.

Shaders like ENB ReShade are known to cause issues and it’s not recommended to use them.

If that doesn’t fix it, try deleting the Online folder in the Data folder which can be found in the install location of your Skyrim. (ie. Skyrim/Data/Online) Potentially some corrupt UI files create the problem.
Connection failed (Hamachi)
You are either using the wrong ipV4 address or Firewall is blocking it. The firewall fix can be found here.

Potentially the server you are trying to connect to is running on an outdated server version. The server host should manually delete the server file and let Harbor redownload it.
​
Stuck on installation/installation aborted
If your installation of Harbor either gets stuck or aborted, try the following:
1.Go to Control Panel
2.Click on Uninstall a program under Programs
3.Remove Harbor
4.Run the Harbor installer again.
NOTE: You must do this from the Control Panel > 'Programs and Features' and not Windows 10's 'Apps & features' or it will result in an error.

If this doesn’t work, then you could use our Skyrim Together Automatic Installer tool, found here, the instructions for STInstaller can be found on the same page.

Potentially it could also be your antivirus interfering with the installation, if that’s the case try disabling it during the installation. Or follow the steps to add antivirus exceptions here and here.
​
Right-Ctrl key
If you don't have a Right-Ctrl key, then we have the following workaround until we have a fix.
Download the file and right click > extract, to extract it to a folder (you can extract it to the Skyrim Folder if you wish) You may need a program to extract it like WinRar or 7-zip.

Remember to read the included Readme!
Skyrim Together logo in single player
If you get the Skyrim Together logo when starting Skyrim like normal, worry not. Skyrim Together currently replaces the intro screen but doesn’t revert it to it’s old state. For now you can ignore this and just keep on playing single player like normal.

You can always make sure you aren’t playing Skyrim Together by looking at the top right while playing, if there is no watermark, then you are not playing Skyrim Together.
Crash to desktop upon loading a save / creation of new save
This could either be a corrupt save or corrupted UI files creating the crash. Try creating a new fresh save. We recommend connecting after completing the Intro sequence and Helgen cave. We also recommend saving while disconnected. 

A possible fix for crashing to desktop upon loading a save is the following:
1.Load a previous save that does not crash
2.Create a New SAve and then type player.kill into the console (you can open/close the console using the ~ tilde key)
3.Load your save that would crash to desktop
4.Open the console again and type player.kill again and try to save again.
If that still doesn’t work, try a complete reinstallation of Skyrim Together and potentially a reinstall of Skyrim itself too.
Fraps / recording programs
Fraps and other recording programs (ie. Bandicam) may cause issues while running Skyrim Together. Unfortunately the only fix is to not use them while playing Skyrim Together Nightly Builds.
​
Disable Pausing Alt-Tabbing
To disable pausing while alt-tabbing/tabbed out, try the following fix:
1.Navigate to Skyrim.ini within `\Documents\My Games\Skyrim` or `\My Games\Skyrim Special Edition`
2.Add `bAlwaysActive=1` under `[GENERAL]`
3.Save the file and the game will no longer pause when alt-tabbed or unselected.
Creation Club error/crash while loading
1. Go to `C:\Users\[USER]\Documents\My Games\Skyrim Special Edition`
2. Open `SkyrimCustom.ini` or create if missing
3. Add the following line to the file.
[Bethesda.net]
bEnablePlatform=0
No port line/info
As of the latest server release which introduced the new Network Library, the ports line will no longer show up when running the server 

As long as the value “started” shows up, it means that the server has started successfully.

0B @ 0B/s
If you can't download the mod through Harbor, here's a link to a manual installation folder, make sure to read the !README! file: https://drive.google.com/drive/folders/1zMiDVWqGzvv5Sth2X9hz4SYs45QWzQ_L?usp=sharing

It’s very likely that files used by Skyrim Together are deleted when they are detected, to prevent this from happening we recommend following the guides for anti-virus exceptions.
Skyrim Together is a Trojan?
Unfortunately there’s a bigger likelihood of Skyrim Together/Harbor being flagged as a Trojan because the program is unsigned and trying to do things similar to certain trojans.

Do not worry, that is a false positive because the code is similar to how malware does it, see this (method 1). What st_loader.exe does is to check if Steam is running, start it if it is not and then start Skyrim and inject our DLL. When there will be a signed DLL and executable it should disappear, for now we don't have a certificate to sign it.
Server.exe only shows one line
That's normal, the nightly builds video guide is over 2 years old.

Modding
Although we don’t recommend modding the game, to increase stability and give the developers more crash reports, that have more usable data. You can still mod Skyrim like normal. To do that, you can follow the following guides for every method, with or without a mod manager. 

Skyrim Together will work well with mods created with the Creation Kit (such as Beyond Skyrim: Bruma). Mods created with SKSE may have trouble with synchronizations as it may contain functionality that is unknown to the vanilla game itself.

One of our Community Helpers, Asahiro has made a way to provide an extensive modding guide for Skyrim Together, which can be found here.
