I have no clue what I am doing. None of anything I read makes sense I'm just trying to load this for my son so he can get mods. When I try to download forge and open it gives me an X and tells me I must open 1.7.2 manually first. I'm running windows 10. I really could use some help as I really know nothing about Minecraft or Forge.

Alright. If your son doesn't know how to download forge, he most likely doesn't know how to use it. But ok, ill guide you.

 

1. Make sure you run the version your forge is based on at least once. So if you download forge 1.7.10, you have to run minecraft 1.7.10 at least once so it can download the components needed for forge 1.7.10.

2. After that, open the installer for forge 1.7.10. If it has an issue about java runtime, download the latest java here: http://www.java.com/en/download/win10.jsp

3. Choose client install (Should already be selected) and then click "OK", it should download.

4. After it says installed correctly, open minecraft and drop down profile at the bottom left.

5. It should have a new profile called "Forge". Click on it and run it to install the last few components of forge.

6. To access the mods folder, go to search and type EXACTLY: %appdata%    Then press enter.

7. Click on the folder called: .minecraft

8. find the mod folder

9. Put your mods in. (Have to be your forge version! Which is 1.7.10 mods in your case)

10. Relaunch minecraft

11. DONE!!!
