This is what I get after I try to run Forge on minecraft.

Install Java 7

2. Start up the minecraft launcher

3. Go to edit profile

4. Click the checkbox that says Executable

5. Delete the words in that box and paste in this:

C:\Program Files (x86)\Java\Jre7\bin\javaw.exe



[Things to note]

Under "Program Files (x86)" the Java folder should have  both verisons of java 8 (to run normal minecraft) and java 7 (to run the forge)


- When you edit your profile in the minecraft launcher, make sure "C:\Program Files (x86)\Java\Jre7\bin\javaw.exe" is linked up to java 7... Or else it will be on java 8... This causes minecraft to load up, and immediately crash.
