After Installing NMM (No mods involved) game stopped booting properly

[Achinon]

Hi there!

So, before the NMM for FO4 i was installing the mods manually and everything worked...

But then the NMM support for FO4 came and i decided to install it. And pretty much that's
the problem. After installing it, the game just won't start. Crashes after like 2 secs of the
game's intro movie. Never had any issues with it before (The game).

 

Things I've tried:

- Uninstalled all mods I had installed before.

- Verified game cache. Like 6 times.

- Removed the game and redownloaded it again. It will not boot even though it's purely fresh out of Steam.

- Uninstalled NMM

- Running the game in window mode; border/borderless

 

My rig (If this gives any help):

Intel i5 4670k 3.40GHz

GTX 780Ti

16GB RAM

Running on Windows 10 Pro

Got it working. Deleted the entire "C:\Users\UserName\AppData\Local\Fallout4" folder so it would get generated once again by itself.

I tried deleting the Falloout4 folder under Local and it still didn't work. How do I delete the entire thing like you said? I tried uninstalling NMM then deleting the Fallout4 folder under Local, and when I ran the game, it still crashed. I checked and it restored the folder but still wouldn't let me boot up the game. Then I decided to undo the changes NMM made me make to the .ini files and then deleted the Fallout4 folder under Local, and I had the same result. Only this time instead of five items in the folder, there are two. I've tried every option I can think of, but you've seemed to have figured it out. Please help? D:

I'm having a similar problem.

 

The game ran like a charm yesterday, and I had been using NMM along with about 5 or 6 mods the whole time I played it yesterday without issue

 

Today, I uninstalled the classic dialog menu mod before booting up the game for the first time. When I launch the game, it crashes within 5 seconds.

 

I tried uninstalling NMM along with all the mods, restoring the ini files to their original state, running the game in windowed bordered/borderless, and both downgrading and upgrading my graphics drivers, but with no luck.

 

EDIT: More info:

I read on Reddit that save files can corrupt, causing the game to crash. Tried deleting my saves, no change. Also, tried OP's fix (moving/deleting ini files so new ones would generate), no change

 

My rig:

Windows 7

Intel 4690k

I got it working, but I undid the changes to my .ini files, and deleted the fallout4 folder under local, then uninstalled NMM, uninstalled FO4, re-installed, and now it's working

All this uninstall/reinstall shouldn't always be necessary:

1. start by uninstalling all mods and manually delete all left over files (like .esp files and the'texture','mesh' etc. folders) in (...)/Fallout 4/Data.

2. delete the .ini files under (...)/Documents/my games/Fallout4/ and all files under C:\Users\UserName\AppData\Local\Fallout4

3. move Savefiles and or delete them from the original folder

4. validate game files

5. Start the launcher and make sur it automatically detects you settings.

A normal uninstall reinstall mostly fixes nothing as the files causing problems are left alone as they are edited/added and will still be active after the new install.

If something is corrupt and causes a CTD It's much more likely to be one of those lose files rather than an actual game file that cannot be repaired by verifying the game cache.
