After fixing this, when trying to open the server (by pressing SeverStar.bat) i have for direwolf 1.7.10 this is what I get http://puu.sh/hPN78/f47c606a12.png
I tried opening it with minecraft_server.1.7.10.jar , but that kicks anyone trying to get in.

Edit:

I went to the location mentioned in console, created a folder called "Server" and copied everything from the client folder inside. After that this is what I get: http://puu.sh/hPO2u/a60becd84a.png
And I can't find where to mess with ram for the server.

Edit 2:
After that, I installed the 64 bit version of java (offline version). And when I try to open the ServerStar.bat , it loads for a while, but this is the end of it http://puu.sh/hPOSg/f2bc5d671b.png
