Minecraft Forums

hi, okay so my computer was full of junk so I had my dad replace the hard drives and make it like new. I kept all my saves, mods, screenshots and resource packs, but downloaded java 8, the latest minecraft.exe file and minecraft forge for 1.7.2 (latest). My problem is, every time I try launching it just disappears and gives me this message:

Please help me.. and thank you.

i know nothing about code, but something like this happened to me before, i deleted the mods i had and that fixed it for me, but when it happened to me there was no crash report or message.

Ugh, but I want the mods. It was working before I restored my computer. I have a feeling it has to do with either a minecraft .exe file update or java. forge is the same.

huh? are you saying it has to do with java? cuz i am seeing it everywhere on the crash report.

OMG I LOVE YOU THANK YOU SO MUCH IT FIXED EVERYTHING!! I had lost hope, i thought i was never going to play minecraft with mods again :'( thank you again
