Hi, just posting here on the off-chance that somebody might know a solution.

I have “Old Gen” Fallout 4 GOTY (GOG 1.10.163.0) installed on my C drive (which is my only drive). I am running the game via F4SE in Vortex. I have meticulously followed The Midnight Ride (TMR) guide - except for using Darker Nights instead of Lightweight Lighting - and installed everything in the order presented in the guide, including the Visuals section.

TMR does not include the FallUI series of mods, though I believe it did at one point. So I decided to install it myself. It seemingly installs normally and is showing as “Enabled” in the mods section. I notice that it does not have an .esp in the plugins section, but I’m assuming that this is also normal ?

Anyway, when I start the game up FallUI HUD is indeed present in the MCM menu. However, whenever I choose “Layout” I always get the following error message :

Wrong HUDMenu swf found.
You need the HUDMenu.swf from Fallul HUD.
Please check your Fall HUD installation, that it is installed and not overwritten by another mod.
Also check that you have enabled the archive invalidation in your ini correctly.

File location:
Fallout 4NData\Interface \HUDMenu.swf

I understand that for most people what rectifies this is to enable archive invalidation by editing the Fallout 4 ini files, of which there are three :

Fallout4.ini
Fallout4Custom.ini
Fallout4Prefs.ini

The lines you are supposed to add if they are not present (or edit if they are present and the values are different) in order to enable archive invalidation (I’m assuming this is the same thing as “enable loose files” ?) are :

[Archive]
bInvalidateOlderFiles=1
sResourceDataDirsFinal=

I have edited my Fallout4.ini and Fallout4Custom.ini files accordingly (via Documents->MyGames->Fallout 4) but it simply doesn’t make any difference : I still get the “Wrong HUDMenu.swf found” message when I choose “Layout” in the FallUI HUD MCM. I even tried adding these same lines to my Fallout4Prefs.ini but again, no joy.

I have also tried adding the following line under the [Launcher] section in the Fallout4Prefs.ini :

bEnableFileSelection=1

But again, it makes no difference : same “Wrong HUDMenu.swf found” error.

I’ve been googling this issue for about two weeks now and I have no idea how to proceed. The error message says to check that the HUDMenu.swf is not being overwritten by another mod, but I don’t think it CAN be being overwritten by another mod because when I uninstall FallUI and look at the Data/Interface folder, there is no longer an HUDMenu.swf file present. Also, without an .esp how am I supposed to move FallUI in my load order ?

As I say, I have thus far followed The Midnight Ride guide to the letter. The only extra mods I have added so far are : Darker Nights, Reverb and Ambience Overhaul and Lost Audio Tweaks, and the problem existed before I installed those mods anyway.

I am totally stumped and posting here in case somebody more knowledgeable might have any bright ideas. I really don’t understand this stuff and merely try to carefully follow instructions.

*This may be relevant : I also tried to install High Resolution Texture Pack 2k and 4k - Valius. Once again, the mod shows as “Enabled” in the Mods section of Vortex, and once again the mod does not have an .esp, but when I go into the game the textures are still vanilla. So I’m guessing that both Valius and FallUI HUD require archive invalidation to be enabled in order to work, but despite my ini edits it is still NOT enabled for some reason ? If so, why could this be ?

Before someone suggests it, I know I could change to Mod Organizer 2 - and at some point I might do - but I would rather use Vortex if there is a solution. I have modded Skyrim AE using Vortex (216 mods) and am 270 hours into a fantastic playthrough of that game, so no problems (for me) with Vortex and Skyrim.

Any help would be appreciated. Sorry for the long post.
