¶ I want to do a fresh install for NV:MP, but I'm unsure about the best way to do so, how do I do it?
Uninstall the game using Steam, then check the Steamapps/Common folder and delete the Fallout New Vegas folder if it remains. After installing the game again, launch it and load up an existing save file or start a new game up until pressing “No” on the Hardcore prompt at the end of the Doc Mitchell intro, be sure to save afterwards to have a clean unmodded save file for any future fresh installs. This process will create the fresh .ini files. Install NV:MP again and it should work right away.
If you would like to keep a separate installation of Fallout New Vegas for modded singleplayer purposes, rename the game's directory in the Steamapps/Common folder. An example would be “Fallout New Vegas Singleplayer”. This should also be done in the Documents/My Games folder for the “FalloutNV” folder. From there, you can uninstall and reinstall the game via Steam. Launch the newly installed New Vegas in a similar fashion as stated above to create a new FalloutNV folder. You will now have a second, fresh install of the game that can be used to install NV:MP without any worry of needing to remove any pre-existing mods.
¶ How to uninstall Fallout New Vegas
For Steam:
- Open Steam and go to your Library.
- Find Fallout: New Vegas in the list.
- Right-click on it and select Manage -> Uninstall.
- Navigate to
C:\Program Files (x86)\Steam\steamapps\common\and, if present, delete the Fallout New Vegas folder. - Navigate to
C:\Users\%USERPROFILE%\Documents\My Games\and delete the FalloutNV folder.
For GOG:
- Open GOG and go to your Library.
- If you used offline installers then run the unins000.exe file in the game's Root folder.
- Find Fallout: New Vegas in the list.
- Right-click on it and select Manage Installation -> Uninstall.
¶ I have a translated copy/version of the game and I installed the mod, but when I click to authenticate the main server, I can't get past the Mod Dependencies prompt where one file has a red symbol and two have a yellow one
This is an issue caused by your translated game having a different FalloutNV.esm than the server's copy, which is an English FalloutNV.esm copy. Any translation changes FalloutNV.esm's integrity. The fix for this is to change your game's language through Steam itself.
To do this, go into Steam, click on Library and find Fallout New Vegas and right click on it, click on properties and select the Language tab, then select English as your language. If you're doing this whilst you have the game already installed, it will basically act as an update to the game and you should be able to download the other two dependencies and play NV:MP. If this doesn't work, uninstall the game, set the language to English and install it with the language set like that.
If you're on GOG, you will have to either change language through there or get another English GOG copy.
For Fallout New Vegas RU players: after switching the language to English, be sure to go into your game's Data folder and deleting FalloutNV.lang file, which is completely useless on the English version and in fact will actually make the loading longer because it doubles the entries that FalloutNV.esm has, making them load again for another unecessary time. When you're done with playing NV:MP, switch to your preferred language (RU, CZ, PL) and verify integrity to get FalloutNV.lang back, as it is required for the Russian/Czech/Polish main menu translations, primarily fonts.
¶ The launcher and game works, but I keep crashing mid-play session
Fallout New Vegas is infamous for its random crashes, and by extension this applies to any and all modifications to the game. NVMP is still in development, so it's likely you'll experience crashing. If you do crash, it is recommended to submit your crash via the automatic bug reporter that opens after a crash occurs.
Some players have experienced more crashing happening with the 4GB installation of NV:MP (as of 3.82+). Please see if removing this, and making sure New Vegas Heap Replacer is not enabled. It is also recommended that you install New Vegas Anti-Crash (NVAC). The number of crashes you experience may be reduced if you are using NVAC.
¶ I have the GOG version, but even when I use the Edit Game Directory option in the NV:MP Launcher, the Mod Dependencies prompt doesn't want to download the required dependencies
This is because the Mod Dependencies prompt is only made to detect dependencies within the default Steam Fallout New Vegas filepath that it was set to detect, even if the Steam version isn't installed. This filepath is C:/Program Files (x86)/Steam/steamapps/common/Fallout New Vegas/Data. Chances are if you own the GOG version, you don't have this filepath anywhere in your PC. The fix is to create it.
First, go into your GOG installation's Data folder and copy FalloutNV.esm. Go into C:/Program Files (x86), create a Steam folder, then a steamapps folder inside it, then a common folder inside the steamapps folder, then a Fallout New Vegas folder into common and a Data folder into the Fallout New Vegas folder. Inside this data folder you will paste the FalloutNV.esm file that you copied. With this, you should be able to download the two other dependencies. However, this process isn't done yet.
Once the two dependencies have downloaded, cancel the authorization process completely and go back to your “Steam” Data folder. You should have two .ESP files named NVMP Q Patch and NVMP Rebalance. Copy them and paste them into your GOG installation's data folder and then you can properly authorize and NV:MP will work like normal.
If the process above doesn't work, you can create the entire Steam Fallout New Vegas filepath, however this time you don't create the Fallout New Vegas folder, but instead you dump the entire GOG game installation folder (with the folder name set to Fallout New Vegas) into that steamapps/common folder. Once you've done that, Edit Game Directory and set it to your GOG copy now located inside your fake steamapps/common folder.
If this process doesn't work either, then the only course of action would be buying the game on Steam or waiting on GOG support to be completely fixed.
¶ I have TTW installed using MO2's virtual folders function, which should leave the game installation directory unscaved, why is NV:MP refusing to work?
¶ I get an MOTD error when I try to join a private server
If you've received an MOTD error, it means that you successfully made a connection to the server as a player - but your client didn't follow up with the first “Message of the Day” packet in time (maximum time allowed in CO:OP servers is 1 minute 30 seconds until the player is kicked). This packet tells the server you're ready to be synchronized.
There are a few potential solutions, the first is seeing if removing a 4GB patch to FalloutNV helps. There is a temporary issue with the 4GB patch that may cause NV:SE to prevent NV:MP from sending communications to the server. If this doesn't help, then the next point of call is to make sure you don't have an NV:SE plugin that is interfering. The last solution we can offer is seeing if you have too many mods being loaded for your CPU to handle. Again, if you take longer than 90 seconds - then the server thinks you're unresponsive and disconnect you.
¶ I can launch the client, but when I try to join a server it crashes right back into the NV:MP client
Please make sure you have run the game after installing at least once; trying to run NV:MP without having first run Fallout: New Vegas can present some issues that make the mod unplayable.
¶ Do I need any DLCs to play on the main server?
Yes. All of the DLCs are integrated on the main server thus You need all the DLCs apart from Courier's Stash. Otherwise you can't join the server.
¶ I keep getting the error saying New Vegas is not installed
This is a common issue that usually happens when New Vegas is not installed in the correct place. The game needs to be installed on the same drive that Steam is on. For example, this is what your directory should look like for New Vegas - C:\Program Files (x86)\Steam\steamapps\common\Fallout New Vegas
Also be sure that your NVMP Client/Launcher is installed within the Fallout New Vegas directory.
¶ Clicking new save or continue in the Fallout New Vegas menu is not doing anything, and is not creating a new save
Go to C:\Users\%USERPROFILE%\Documents\My Games\FalloutNV and delete Fallout.ini
