Confused :c (How do I install WA and LN together ;w;) [SOLVED]

Okay, so, I've downloaded the base game, generations, ambitions, late night, pets (fixed), seasons, supernatural, showtime, 70s, 80s and 90s stuff, town life stuff, island paradise, university life, movie stuff, outdoor living stuff and world adventures.
While I waited for world adventures, late night and ambitions to download, i installed most of the other expansion packs and started playing and it all worked perfectly fine (thank you) but now that late night, world adventures and ambitions have been downloaded, i want to install them, so i read the late night instructions and uninstalled everything...
but in the instructions for late night, it says to not apply the cracks for world adventures
forgive me if i'm wrong, but there are many cracks for world adventures and it seems as though you can't progress to other steps when you install it.

so now i'm really confused about what i do
do i just, idk, install world adventures completely as it is or just do this


"8. Now completely close the Game including the EA Download Manager from the System Tray. Open
the 'Sims3EP01Setup.exe' in this .rar file. Follow on screen instructions to Install the 
Game. When a Serial code is needed, use one of the following Serial codes:


3P55-ZXKE-ALJN-KALG-SRLD
WYGY-KFHB-PPSL-JPPQ-QRLD
LAJ2-B2W9-KDGZ-AKDE-5RLD

S8ZZ-7DVX-U7NY-UU7L-4RLD


9. Start the The Sims 3 launcher. You'll get a message that you're version of the Game is not
compatible. Click 'OK'. You're now on the Update window. Check the box inf front of the 
'SIms3_2.5.12.004002_from_2.0.86.00.2002.exe' and click 'Update now'."

then leave it?

i'm so confused can someone clear this up for me? sorry for sounding like an idiot but it seems like i'll break my hardrive if i just skip everything
i tried searching for how to install world adventures and late night, but they seem to come up with questions for solely world adventures or solely late night, not how they link together, so could someone please help me out here?

... okay so i didn't apply any cracks to either sims 3 or world adventures, but now when i try to instal world adventures, it says that sims 3 has to update and it fails then shoots itself in the foot
so
do i follow the cracks of world adventures or not? ahhhhhhhhhhhhhhhhh i'm so confused

Thank you in advance!

1. Install The Sims 3 and all expansions you like, but install AT LEAST one of the following expansions: Movie Stuff, Island Paradise, University Life, 70s, 80s, & 90s Stuff, Seasons, Supernatural, Diesel Stuff, Katy Perry Sweet Treats, Showtime, Master Suite Stuff, Pets, Town Life Stuff, Generations.* (You may skip all the "# Crack" folders. You DO NOT need to use any "# Crack" folders!)
If you get an update error when trying to install any of the expansions, do step 2 first and then continue with step 1 again.




^okay so i do step two and it'll do its thing and i'll install world adventures without a  update error problem? and do i just disregard every crack folder in all the expansion and stuff packs? what about for the base game, do i have the cracks or not? sorry for all this haha i just want to make sure it's all good.
thank you

sorry, but i think i should also mention that english is my second language - i primarily speak thai at home, and the structure of sentences is a bit different (i'm fluent in both, but i usually read and speak in thai)
sorry!
