Launch.Bat doesn't start a server


Question

Posted

Title: Launch.Bat doesn't start a server

Version: 3.1.2

OS: Windows 7 home premium

Java Version: 6.0.290.11

Description of Problem:

I just recently wanted to try out tekkit. I've been able to host servers fine before, I've port forwarded and everything. So I downloaded the launcher and the server, I started the launch.bat for the server but it never finishes. It gives some things which I assume to be errors and just stops. It doesn't say "press so and so to continue" or anything, it just doesn't do anything more.

I just figured it out- that was the problem. I only had the 32 bit installed, once I installed both 32 and 64 both the server and launcher worked fine. And just having "java" instead of a path worked good too, thanks for the help!
