Unable to access jarfile Tekkit.jar

Hello everyone I am new to these forums and I hope you can help me.

I downloaded the server client today and extracted everything to a folder and yada yada...

When I launch the bat file CMD comes up but nothing happens. I get no error message. All it says is press any key to continue and when I do it closes. It does nothing. I have JAVA 7 64 bit on Windows 7 64 bit. I downloaded and installed the single player launcher successfully, I just want the server to work on my local network so I can play with my brother like I do on Minecraft vanilla.

EDIT: I managed to find an error message. Apparantly there was an error message displaying but it was opening and closing so fast that you couldn't see it.

It says "Unable to access jarfile Tekkit.jar".

Launcher/pack Version: 2.1.1
Operating System: Windows 7 Home Premium 64 Bit
Version of Java: 7.0.0.147, 64 bit
Description of Problem: Launch bat file does nothing.

Error Messages: Unable to access jarfile Tekkit.jar

Please help! I attached a screenshot of what happens.

Thanks

Does no one else have this problem?

Seriously I extract everything in the zip to a separate folder and then click launch and I get this message. Is there really NOBODY who can help me even in the slightest bit?

I had this problem and i right clicked on "launch" and swapped what it said with this "java -Xmx1G -Xms512M -jar Tekkit.jar nogui
pause" and it works now

So editing the memory constraints could work.... intriguing

Mine still doesn't work...

Does it have to do with your set java heap size under control panel maybe?

I really hope my persistence for a fix for this isn't categorized as spam but I'm getting really frustrated as there seems to be no fix for this...

I don't know what I did but now it is working

i have the same problem and i have tried the (java -Xmx1G -Xms512M -jar Tekkit.jar nogui)

didnt do a thing for me...need help

perhaps learners never knew,RESTART UR CPU(Computer)FOR YOUR SERVER TO WORK

Thank you
Thank you
i had a problem but i fixed it with restarting

restarted my comp and yet again it failed
any more ideas

my friend is getting the same error. what i want to know, zilecsi, is how you knew to the initial and maximum heap sizes to 1gb and 512mb?

I had this problem until I opened the launch.bat file and before the command that's already written there, I navigated to where my Tekkit.jar file was stored

Originally the file (launch.bat) looked like:

java -Xmx3G -Xms2G -jar Tekkit.jar nogui

pause

which I modified to:

cd C:\Users\Ben\Desktop\Minecraft\server

java -Xmx3G -Xms2G -jar Tekkit.jar nogui

pause

cd is the change directory command in Windows command line, obviously that directory is going to be different for any one else, so you just need to change that line to where your Tekkit.jar file is

Hope that helps others

In order for terminal to be able to access the folder you have to type "cd" (without the ") then a space and then drag the tekkit server folder into the terminal. Once you've done that just copy and paste the launch.sh into terminal and hit enter.
