Adding map in Tiberium wars and Kane wrath on windows 10

Hi everyone i need you help.

I'm having a problem to add maps to the game, after following few guides to do so with no success.

the guide tells me to open a Maps folder in the C:\Users\[user]AppData\Roaming\Command and Conquer 3 Kanes Wrath

after i did it i've lunch the game and didnt saw any change.

with other guide i saw they told me that:

1. once edit is open hit HKEY_LOCAL_MACHINE

2. hit SOFTWARE

3. hit WOW6432NODE

4. hit Electronic Arts

5. hit Electronic Arts again

6. click on whichever CNC game you want to add maps to.

7. once you click on whichever game you want to install.

8. once there on the right of the game folder there will be 3 files, you need to add one more to the registry to install custom maps.

9. right click inside the directory on the right and hit New - DWORD (32-bit) value

10. for the new value type in - UseLocalUserMaps - and click anywhere to save the regedit.

11. close regedit and good to g

12. continue to do what MaD does to install custom maps.

again it didnt works... 

please help me.
