This has been a problem for a quite a while now as all of the mods that I install refuse to activate. This has been going on with all games (Witcher 3, Witcher 2, Fallout 4, Skyrim, Skyrim Special Edition) and I've tried looking at other forums but no clear answer is present with the topic seemingly never happening before. What basically happens is I install for example the Unofficial Skyrim Special Edition Patch and try to install/activate it when it stops automatically, saying 'Problem occurred during install:' but nothing afterwards. I just want some mods for Skyrim SE without using Bethesda's mods and getting achievements disabled. I've already tried changing installation directory and reinstalling the game.
Thanks in advance.

63.17 didn't allow for sorting plugins and now 63.19 doesn't fully swap profiles (uninstalling one profile and installing a different profile) - only installs 1 mod for me.

I have the same problem with fallout 4 in fact to have an opportunity to install it I have to give the button 50 times +/-.

that if before this I tried to uninstall a mod so that the game was faster and I crashed completely, after that uninstall nmm and reinstalled but I gave all kinds of errors if I opened the program or anything else in it , he said to me (an error has occurred and nmm has to close) luckily now he does not say it to me so often.

I am using the google translator so I apologize in advance for my English

Popularly known as breaking down part 2.This film was released in theatres on November 16, 2012. Twilight movie in hindi. Some of critics hasgiven negative response for this film.

This issue only happens to me whenever i leave nmm and go to something else like chrome when the mod is still activating. i usually have to restart nmm to activate it.

Another quick simple fix i found was to run the program as administrator and click the gear icon, under the general section under associations make sure all the boxes are checked, if this dose not work i would recommend manual installing it, i personal do this to keep the nmm as organized as possible. Anyway let me know if this helped at all

Whenever I install a new mod for NMM (Version 0.71.2) [Skyrim Special Edition]. The mod fails to be activated. No error messages. I have all the requirements- some mods activate just fine. Others don't. I purged unmanaged files and thought maybe that works? I just ended up deleted files I needed for racemenu and animations. Which is why I'm not here. I'm here BECAUSE mods won't ACTIVATE. This is very annoying and I do not won't to switch to a different mod manager. IS there anyway of fixing this issue? PLEASE DO TELL!!!

NOTE: I see Mod Activation installing.. loading but nothing happens. Mod is still not activated!

Update: I was told the reason behind why NMM won't install 'said mod' [when the fomod doesnt have a data directory that's why]. So I have to pretty much install the 'mod' manual and that's a pain. If the mod has any issues. Uninstalling it, is gonna be a pain. I HOPE NMM could work with fmod mods better in the feature.
