Why wont mods work in C&C generals zero hour?

Probably because the mod is not for that updated version of your game, has to match to work most of the time..

global crises mod for zero hour works perfectly on the ultimate game of my windows 7 Premium 

three steps, and its going to take a few mins.

step1

go to bibber.eu

click on c&c generals zero hour

download c&c generals zero hour launchers

step 2 THIS IS CRITICAL

make sure your mods file location is as folows

Which ever drive your game is located C,D,E,F

program files(x86)

origin games------------this is the important thing right here

command conquer generals zero hour

step 3

go to your game library in origin

right click on zero hour

game properties

uncheck the box that says enable origin in game for command and conquer generals and zero hour.

if you have the ultimate edition, repeating these same steps for all game modding should work. this is all it took for me to get the mods working on windows 10.
