confused guy

I deleted everything from technic pack and only redownloaded the launcher, which isn't running. So I don't have the server launch.bat yet or any of the multiplayer stuff yet. But for some reason, java is not opening in the control panel when I select it. I must be doing something wrong there.

Alright I'm absolutely sure that I have Java 7 update 4 for windows 64 bit. I even reinstalled it and did their website test thing to see if it works. Then I restarted the computer. I then deleted everything from the launcher and all it's files. I then redownloaded the launcher exe. Still the same problem.

OK now I am trying to delete this server and start fresh... again. But now it says the file is open in another program, and there is no program running it... Also, does the launcher support java 7? Or is the problem that I have to downgrade?

Then what could be wrong with my stuff? The launcher should at least start shouldn't it? This flash of a second where it stats is taunting me like crazy.

Did I see something on the website about a 1.2.5 minecraft update? Is that where I'm going wrong? Is there a special thing for that, that I have to download?

I am running the server with 7 already. How do I run the launcher with 6?

Alright, I backed up the world and deleted the server. Put in the IP and started up the new server and i got the error: C:\Users\Me\Desktop\Tekkit 2>java -Xmx3G -Xms2G -jar Tekkit.jar.... You know what, It's the same error. Sorry. Also, I don't quite understand why the server affects the Launcher working. I know the java is correct... I'm stumped.

Sorry it's "-jar Tekkit.jar nogui". You're right. Also, I downloaded the launcher again from the front page of the technic website. Same problem.

launcher v 1.0.1.3 Windows 7 64 bit Java v 7 update 4. Java website's test says it's working fine. Hi, I've been trying to get my server working because I haven't been on it in quite a while. When I try to start the server, I get an error saying: C:\Users\Desktop\Tekkit Server 1.1>Java -Xmx3G -Xms2G -jar.nogui Error occured during initialization of UM Java/lang/NoclassDefFoundError: java/lang/Object C:\Users\Desktop\Tekkit Server 1.1>pause Press any key to continue... That's that. Also, as of late, when I start my launcher, I get the "getting launcher Version" flash at me before it just shuts down. If I could get help for these problems, I would be very grateful.

Hello. When I run my Tekkit server, I can play fine for about five minutes before i get a horrible lag spike, and then I crash. Any idea why?

Thanks!

Hi how do you make it so that the option to switch to creative mode isn't there? I know you can just press "O", but I'd like that option not to be available for when my friends join the server.

Ok I fixed mine. My IPV4 address or whatever changed on me. go to cmd and type in ipconfig to find it

I'm getting the same message but I don't have any other servers running.
