Gee, i wonder if you bothered to read the common problems and solutions sticky.

Alex311360 · June 15, 2012

Actually, I did. I saw something about Tekkit, but it wasn't related to my problem

Torezu · June 15, 2012

Gee, i wonder if you bothered to read the common problems and solutions sticky.

It's not actually the CP&S sticky, but it is still a sticky that shows this exact error (for a different mod) and the solution.

Jay? · June 15, 2012

It used to be in the Common problems and solutions sticky. I'll readd it shortly.

In the mean time, OP Update your damn java.

Alex311360 · June 15, 2012

However, it appears to be not IC2Machines, but Nether Ores.

Torezu · June 15, 2012

However, it appears to be not IC2Machines, but Nether Ores.

That's why I said "this exact error (for a different mod)" - the solution is the same, though.

Alex311360 · June 15, 2012

Just got the installer. This could take a while :/

Torezu · June 15, 2012

Also, make sure you delete older versions of Java, as they can confuse the issue quite a bit.

Alex311360 · June 15, 2012

It finished, but it's still trying to load Jr6, what do I do now

Jay? · June 15, 2012

Come on dude.

Alex311360 · June 15, 2012

YES I DELETED IT

>:C

Jay? · June 15, 2012

Are you still directing your server to use java 6?

Alex311360 · June 15, 2012

What the code is now:

java -Xmx3G -Xms2G -jar Tekkit.jar nogui

pause

That's what launch.bat does.

Alex311360 · June 15, 2012

The error:

C:\Users\Alex\Desktop\Tekkit>java -Xmx3G -Xms2G -jar Tekkit.jar nogui

Error: could not open `C:\Program Files\Java\jre6\lib\amd64\jvm.cfg'

C:\Users\Alex\Desktop\Tekkit>pause

Press any key to continue . . .

Alex311360 · June 16, 2012

Waiting on solution :/

Nentify · June 16, 2012

If you remove all your Java installations, get JRE 7 and try again, does it still error? When I say delete, I mean uninstall it via the "Programs and Features" in control panel?

Alex311360 · June 16, 2012

Found a fix.

Simply took the launch code from Bukkit, changed it to Tekkit, then re routed the java to program files 86 and it worked!

/closethreadplease

EDIT: Also had to remove Nether ores because it was preventing a mod from working.
