When ever I start up forge 1.7.10 and press play it goes to a black screen for a second and then goes to a tab in the launcher called Game Output with lots of writing. I'm not sure if it's a crash or if it's something else. I've been trying to find an answer for ages now. I have tried re-installing minecraft and forge and tried loading up forge on a different version and still no luck. I am using forge 10.13.4.1448 and haven't installed any mods yet.
Please Help!

Did you manually modify the jar?

I don't think so
Then try deleting the 1.7.10 version folder, then redownload it and redownload forge.

Your 64bit Java is installed in the 32bit programs? You could try to update Java since it is up to build 60 now; maybe it'll help.
Ok I'll try it
Updating Java didn't work neither did reinstalling 1.7.10 and forge
This is a long shot but since you are using Vista it may help.

Just download and place in your mods folder and see if it helps.
Nope didn't work either
