I should start by saying I've been wracking my brain all day with this. I have NEVER installed any fallout mods before, at least not on this PC. I am using the voluntary upgrade to Windows 10 (from Windows 7). I followed the instructions, in order, to a T. Fresh installs of FNV ultimate edition and FO3 GOTY both on Steam. Both TTW instillation and FOMM have ALWAYS been run in admin mode. In addition I apologize in advance for the wall of text but i am being quite specific i assure you! for a summation go to the very bottom of the post.
I ensured i started a new game in both so there are fresh .ini files. I am certain that the FNV directory was correctly chosen at C:\Program Files\Steam\steamapps\common\Fallout New Vegas\ (TTW reads it perfectly.) A bit less certain of Fallout 3, though but the file directory is C:\Program Files\Steam\steamapps\common\Fallout 3 goty\ ( it didnt have the last \ until i properly started the game and generated an .ini so that was done BEFORE attempting instillation on TTW. I was however severely confused by the "pick your own location for TTW specification, ultimately i went with an outdated guide and place it on the desktop in a folder at C:\Users\Default\Desktop\ttwinstaller.
Once i got that all sorted the download went off without a hitch, i downloaded the link to Fallout Mod Manager (FOMM) 0.14.11.12 .
this was a fresh instillation from your link in the instructions, follow by the actual download of TTW from your second google.could link at the very bottom of the download page. After opening it i was prompted to install NVSE as it was necessary (i did) then i installed TTW without a hitch. TTW read FNV and FO3 along with their respective dlcs without issue. (yes i have ALL the dlc installed. i promptly moved the generated main and optional files to C:\Games\FalloutNV\mods (the correct default location.) This is where things took a nose dive.
I opened FOMM and noticed two options, use it for FO3 or FNV i checked both out to see if they had their dlc, both games had their respective DLC properly listed (F03 was out of order but i left it so 4 of them were red.) Their dlc was respective to their game only, contrary to the guides i've used to verify my steps which show FNV should also show FO3's dlc, it does/did not. I used the package manager while viewing FNV and downloaded the first "main" packet after navigating to the proper FNV directory where it was placed. This initially failed with a message "something must have gone horribly wrong." so i overwrote the files with another TTW instillation of them, this worked as it permitted the "main" file to download without issue. "other than asking to overwrite a few of the files, specifically something about cgeneralencouter. I assume this is waters of life or maybe operation Anchorage?
After this i attempted to install the optional file 3 times, i received the message each time that the main file was not installed, so i verified it was by "reactivating it". This seems to be a common issue however your mod is the ONLY mod being/currently installed besides NVSE (New Vegas Script Extender.) which you prompted me to download before TTW installed as it is required. Other posts i have found specify that there is an interaction with using NMM to install it, i will note again i used FOMM as specified.
So to sum it up, I am using the voluntary upgrade to Windows 10 (but lets face it i was pretty muched forced to Bleep you Microsoft!) I followed directions to a T (i'm a super perfection freak). TTW and FOMM are run in ADMIN mode. I have no OTHER mods for ANY game on this PC. There seems to be some inconsistency in the instillation for some reason (glitches?) also i have a few problems / questions:
1: why dosen't my FO3 dlc show under FNV like other peoples in the FOMM, and can this be an issue? If so how do i fix it?
2: Did i use the appropriate directories?
3: How can i get the Optional file to install?
4: If i have to do a manual instillation i am confused about what files to copy from which file. (i have never done this before.) I would prefer to avoid this if necessary.
