Steps to grant admin rights:
- Simply right-click the NMM (Nexus Mod Manager) Icon on your desktop and select Properties
- Navigate to Compatability tab
- Check Run this program as an administrator and click OK

Method 4: Update NMM / Fallout 4 / Windows
There is a possibility that you are running the older version of Nexus mod manager and newer non supported version of Windows 10 or vice versa. That’s why you need to update everything to make sure that Fallout 4 mods work without any errors.
If you haven’t use the latest version of Nexus mod manager there might be bugs and small things that can ruin the game. Hence download or check for the latest version for the NMM at their official website.
Update Fallout 4
If you use Steam client to install Fallout 4, just check for the updates in the Steam app and install it if any update found. Or simply open the Fallout 4 game and go to about section and check for updates.
Update Windows 10
If you have the Windows 10, there is a chance of you running the older version of Windows 10 that is not supported by Nexus mod manager. Go to settings, update & security and click search for updates. Download and install the updates if you found any.
Method 5: The All-New Vortex Mod Manager
Yes, the Nexus mod manager team has officially created this new Vortex mod manager that going to be replacing the Nexus mod manager. All the mods created for Nexus mod manager will be supported on the Vortex as well.
If you still prefer the old Nexus mod manager, here is the link you can download. But I’m not suggesting that since everyone now started to use Vortex mod manager for Fallout 4 and it’s pretty easier to get used to.
Install Vortex Mod Manager
- Go to this link and select Click download the latest version
- Now select the Manual download and the .exe file will be downloaded
- Install that file and give necessary permissions and voila, Vortex is now installed on your PC
From now on you can use this Vortex mod manager to manage all your mods for Fallout 4 and even more if you want to.
Method 6: Enable Multi-HD Install Mode
Nexus mod manager has this cool feature that creates a virtual drive inside your hard drive to make space for the mods you are going to install in the future.
Go to Fallout 4 setup and check the Enable Multi-HD install mode option to make sure the game and mods are installed in the same drive.
Let’s say if you have an SSD for Windows and HDD for the games, by default the Nexus mod manager will be installed on the SSD and it will create a virtual space on there. Hence you need to make sure the game you install (Fallout 4 in this case) and the Nexus virtual drive in the same hard drive for the best results.
Method 7: Uninstalling Corrupted Mods
If you regularly use multiple mods for different games and smash them together like a massive amount of mods can cause some mod file to get corrupted. Sometimes, it is possible to get an error like mods not working when some of the mods in nexus might be corrupted or crashed.
To fix this issue simply disable the mods and open the game till you find the culprit mod that is not letting you play Fallout 4.
Tip: You can use this method to quickly enable and disable Fallout 4 mod
- Open Nexus mod manager
- Select the Fallout 4 and open the list of mods installed
- Now right-click every mod and select deactivate and run the game till you find the corrupted mod
- Once you find it, simply right click and try reinstalling again if that doesn’t work for you then just disable it and run Fallout 4 without any troubles
Method 8: Organizing Installed Mods
One of the most common mistakes that every newbie do is that they install plenty of games and using a crazy amount of mods inside the Nexus mod manager, so even if they want to remove the particular mod, it makes so harder to find them.
There is a way to sort and organize the mods easily with some help of third-party tools.
