From observing the forums, the biggest problem people seem to be having is not knowing how to manually install so many people seem to install Skywind/Skyblivion incorrectly. Sometimes they don't even put the .esm file in the data folder.
So find your Skyrim Data folder. It's different for many people but I believe for most people it's C:/program files/steam/steamapps/common/skyrim/data. If that's not how it works for you, mine is applications/The Elder Scrolls V Skyrim/contents/resources/transgaming/programfiles/ The Elder Scrolls V Skyrim/Data. My directory is weird though because I ported my Skyrim off steam on to my mac.
So basically, the data folders are where you put all the files. You should have folders called meshes and textures. Any files you receive in a mod in a meshes or textures folder should go in those folders. Don't ever overide your meshes and textures folders unless you're trying to uninstall any of your mods that are using custom meshes or textures.
That's a screenshot of the folder. It should look the same on PCs except in the PC format. I have 0 bugs on my Skyrim. It's patched to 1.93 and I have over 100 mods installed and I've never had a CTD or bug. That's because I have a good load order. If you want me to make a thread of how to set up your load order, ask me.
Then, after all the folders are put in the data folders, just check the mod in the Skyrim Launcher and you're good to go.
If you have any more questions please put them here. If you want me to make another thread that will apply to Morroblivion instead of Skywind. Ask.

Hey!
I had a hackintosh, and I was wondering how you ported the game in the first place..?
My load order is:
1) Dawnguard
2) Hearthfire
3) Dragonborn
4) Unofficial Skyrim Patch
5) Unofficial Dawnguard Patch
6) Unofficial Hearthfire Patch
7) Unofficial Dragonborn Patch
8) Purewaters
9) Purewaters DG
10) Purewaters DB
11) Enhanced Lights and FX
12) Realistic Lighting Overhaul
Is that good?
