Problems with Minecraft Forge [1.7.10]

[drg00]

Recently with Minecraft Forge Version 1.7.10-10.13.0.1208 Minecraft Forge won't run at all and when I check the log file it just says that it was unable to launch. I am complete confused of why this won't work because I have been able to play on forge very well in the past.

I don't know if this link will work. Please let me know if I doesn't.

Thanks,

I did read the EAQ, I am positive I did everything right, I did the exact same thing as I have done with 1.7.10 in the past only it didn't work this time. After it didn't work I deleted and redownloaded minecraft and forge, and retried, but it still didn't work, and I know my antivirus software isn't affecting it because it has worked before with it.

I don't know if this will help, or if the link worked but...

Read the EAQ, don't use java 8...

[drg00]

Like I said I have already read EAQ, I am using java 7, not 8.

[loordgek]

here

Java is Java HotSpot Client VM, version 1.8.0_20

[drg00]

How do I get rid of java 8 then, because I installed java 7 before I tried to run forge.
