To install cVc Dead Wasteland

Download 'cVc Dead Wasteland 6 - Core' in your Mod manager and away you go
Installing Manually:
Download 'cVc Dead Wasteland 6 - Core' manually
Drop the file contents into the Data folder of Fallout 4
Activate cVc Dead Wasteland 6.esp in Fallout 4 - 'Main Menu' -> 'Mods' -> 'Load Order'
The Mod will automatically run and be active in your game once it has been added to your load order
You can install / uninstall this Mod mid-game safely

To install the DLC add-ons

These DLC add-ons work in conjunction with cVc Dead Wasteland 6 - Core. They will not work without the Core file. You can choose either or all three DLC Files
Download 'cVc Dead Wasteland 6 - DLC1' in your Mod manager and away you go
Installing Manually:
Download 'cVc Dead Wasteland 6 - DLC1' manually
Drop the file contents into the Data folder of Fallout 4
Activate cVc Dead Wasteland 6 DLC.esp in Fallout 4 - 'Main Menu' -> 'Mods' -> 'Load Order'
'cVc Dead Wasteland 6 - DLC2' as above
'cVc Dead Wasteland 6 - DLC3' as above
You can add / remove these add-on esp/ba2 files at any point during play through without affecting the Core file or your save file. Of course, anything built prior to removing these DLC files will be affected
IMPORTANT
Place the DLC esp file(s) below the Core esp file / example load order:
xxxxxxxxxxxx.esp
cVc Dead Wasteland 6.esp
cVc Dead Wasteland 6 DLC.esp
cVc Dead Wasteland 6 DLC2.esp
cVc Dead Wasteland 6 DLC3.esp
xxxxxxxxxxxx.esp

To update cVc Dead Wasteland / DLC add-ons
Simply download the file(s) and overwrite the existing ESP and BA2 files
NOTE:
If you're updating the cVc Dead Wasteland 6 - Core file from an older version:
v5.0 / v5.1 / v5.2 / v5.3 / v5.3a / v5.4 / v5.5 / v5.5a / v5.5b / v5.5c / v5.5d / v5.5e / v5.5f
to this version v.6.0 / v6.1 / v6.1a / v6.2 / v6.3 / v6.4 / v6.5 / v6.6 / v6.7 you'll need to change the file names if you want to keep anything that you've already built
cVc Dead Wasteland 6 - Textures.BA2 <-> cVc Dead Wasteland - Textures.BA2
cVc Dead Wasteland 6.ESP <-> cVc Dead Wasteland.ESP
It will work either way but, from v5.X to v6.X the file names changed. That's why you'll need to change the file names in order to keep anything built prior to these version 6 updates
If you've downloaded version v6.0, v6.1, v6.1a, v6.2, v6.3, v6.4, v6.5, v6.6, v6.7 and none of the versions 5.X, you won't need to change anything
Be aware that these DLC Add-ons reference 'cVc Dead Wasteland 6.esp' in their file headers. Changing the core file name will remove DLC1, DLC2 and DLC3 from the workshop menu. Ask for a fix file in the forum if required

To uninstall this Mod
Use the holotape in your pit boy (Pit boy / Misc)
Run the uninstall script
Save your game
Exit, deactivate the Mod
Restart the game
The holotape is added to the player's inventory on install, however, one can also be crafted at the 'cVc Crafting Workbench' under the 'Utils' menu or the vanilla chems workbench under the 'Utility' menu. Its ID is: '(Settings) cVc Holotape'

Menu Issues
cVc Dead Wasteland uses script injection to add the menu 'cVc' to the workshop. Installing / uninstalling this Mod will not affect your workshop menu. Of course, anything built prior to removing the Core File or the DLC files in-game will be affected after removal. Be sure to destroy anything built prior to removal
Issues with workshop menus arise due to improper or no uninstallation of Mods. 'Loose' Mods - Mods that only add items to the workshop menu without injection or any other method of installation - are prone to this issue
For example; if you install a Mod that adds a single workshop item to the vanilla water menu, then decide you don't want it as part of your load order, removing it's ESP file from the game in some cases will cause the vanilla water menu tab to disappear.
In cases such as these, to fix this problem Mod authors have come up with a solution; A workshop menu fixer. Amen to the modding community!
If you are having any issues with your workshop menu either prior to, or post installation of this Mod, I recommend using such a Menu fixer
Recommended:
Settlement Menu Manager (SMM) - tested / works

If you are having issues with this Mod not appearing in the game's workshop menu - Try these suggestions:
Check to see if the mod is activated
Method 1:
Boot the game - In the main menu - click 'Mods' - click 'load order' - check that cVc Dead Wasteland 6.esp has been activated
Method 2:
go to C:\Users\your_account_name\AppData\Local\Fallout4 - Open the 'plugins.txt' file (default notepad works fine) - make sure there is an asterix next to cVc Dead Wasteland.esp in the list
Example plugins.txt:
# This file is used by Fallout4 to keep track of your downloaded content.
# Please do not modify this file.
*mod01.esp
mod02.esp
In the above example, 'mod01.esp' is active and will run in-game, 'mod02.esp' is inactive and will not run in-game
Check to see if your game is up-to-date
Go to your executable file, right click on Fallout4.exe, select 'properties' and check the 'version' number
default address - C:\Program Files (x86)\Steam\steamapps\common\Fallout 4\Fallout4.exe
This mod will only run using 1.10.63.0 or above of the game's exe file.
