Skyrim manual installation

[Jaqum]

I've had to delete and redownload the game a couple of times because of a certain mod or me going over 500, help?

[Just Don't]

Which "certain mod"?

500 what? mods? plugins?

Why are you deleting the game instead of removing the mod or mods you added since the last time the game worked?

And what exactly do you want to manually install? The game is handled by Steam, for mods you should really be using a mod manager.
