Solution 1: Run NNM Installer as Administrator

The first reason why the mods could be appropriately installed on your games is that it doesn’t have the appropriate permissions to read or modify your files. This could happen because you have an old version uninstalled that left some data or problems with the permissions.

The easy way to fix this issue is by running NNM with administrator rights. You can do that by right-clicking in the Nexus Mod Manager shortcut, and there choose the option Run as Administrator.

Have you been able to install the mods after enabling administrator rights? You can try to enable that permission permanently following these steps:

  1. Right-click on the Nexus Mod Manager and select the option Properties
  2. Now navigate to the Compatibility tab and there check the box Run this program as administrator
    disable run this program as an administrator
  3. Click on Apply to save the changes

Now you will run Nexus Mod Manager with administrator rights every time you opened it from the shortcut.

Note: Don’t add the administrator rights directly to the executable file because it could create some conflicts.

Solution 2: Disable Antivirus

This is another of the quickest way to fix this issue, disabling the antivirus.

Have been reported multiple times that security software that blocks some important mod files if they find it suspicious or similar to another virus.

If you trust the mod and have downloaded it from the trusty worthy website, like Nexus Mods, you can disable your antivirus temporarily while you install the mod.
