GenPage Posted June 24, 2014 Share Posted June 24, 2014 With the next upgrade in Minecraft and Minecraft mods progressing into 1.7.2, more and more mods are dropping support for Java 6. Before upgrading Java make sure your computer supports it by checking here: http://java.com/en/download/help/sysreq.xml Unlike Windows and Mac, major Linux distributions such as Ubuntu, Fedora or Red Hat Enterprise Linux offer OpenJDK as their default Java SE implementation. 32-bit vs 64-bit and what does it mean? Long story short, you cannot run a computer with more memory than 4GB if you use 32-bit. Technic recommends using 64-bit versions of Java (if supported). This allows more memory for Minecraft to use. Questions or how to check your system can be found here: Windows users: http://windows.microsoft.com/en-us/windows/32-bit-and-64-bit-windows Mac users: http://support.apple.com/kb/ht3696 Linux users: http://stackoverflow.com/a/246014 If you are needing to upgrade your Java install, grab a copy from here http://java.com/en/download/manual.jsp and follow these guides: Windows Users: Check what version of Java your running by going here: http://java.com/en/download/uninstallapplet.jsp Or checking your installed programs by going to: Control Panel -> Programs and Features and following this guide: http://java.com/en/download/help/windows_offline_download.xml Mac Users: You have special requirements for installing/uninstalling Java on your computers Please read CLOSELY here: http://java.com/en/download/faq/java_mac.xml If you cannot uninstall Java 6, install Java 7 and then follow thses steps: Next start the Java Preferences app from /Applications/Utilities Drag Java 7 to the top of the list like in the screenshot. This will make locally run Java applications use Java 7 instead of Java 6. You can uncheck the Java 6 options if you do not want them to be allowed to run. This section is for the Java runtime for local applications, and has nothing to do with the web plugin. Linux Users: Ubuntu and Fedora users: http://openjdk.java.net/install/ Red Hat, SUSE, Oracle, Oracle Enterprise, SLES users: http://java.com/en/download/help/linux_install.xml After you have installed Java 7, check to make sure it is installed here: http://java.com/en/download/installed.jsp Hope this helps clear things up!

NuclearNarwhal Posted June 24, 2014 Share Posted June 24, 2014 (edited) I use a Mac, but sadly the link you provided doesn't help me out much. I have installed Java 7 (both the JRE and the JDK) on my Mac, and when I go into Terminal and type: java -version It will show that I have a version of 1.7. And when I go to the Java Control Panel located in the Mac's System Preferences it also states that I have Java 7, update 60. (The recommended build) But when I launch things such as Minecraft (from the normal launcher) and ModPacks from Technic Launcher it STILL persists to use the default Mac OS X Java 6... I have even tried going into Minecraft's Info.plist and changing the version of Java it is supposed to run to Java 7 directly, but after doing so it says that no compatible version of Java 7 was found. Despite other places in my computer stating that I DO in fact have Java 7 successfully installed. Any help with this would be greatly appreciated... I have already spent many hours looking for an answer on the internet, but to no avail.

GenPage Posted June 24, 2014 Author Share Posted June 24, 2014 What version of Mac OS X are you running? and have you tired these steps: http://java.com/en/download/help/mac_uninstall_java.xml Link to comment Share on other sites More sharing options...
NuclearNarwhal Posted June 24, 2014 Share Posted June 24, 2014 (edited) What version of Mac OS X are you running? and have you tired these steps: http://java.com/en/download/help/mac_uninstall_java.xml Why would I want to uninstall Java 7? Isn't that what I want? Also, I am running OS X 10.9.3. EDIT: Good news everyone! I found a way to get Minecraft to run Java 7! You simply have to run the Bootstrap.jar directly, instead of through the application. I'm not sure why it makes a difference... But it works for me. The only problem though is that I don't know how to launch my ModPack directly. Seeing as you usually do it through the Technic Launcher. But if I do it that way it will still use Java 6 (I think) for when I launch the ModPack from there. MOAR EDITS: Also, GenPage, can you make sense of this crash report? https://gist.github.com/anonymous/a241cc436af47abd74c7 Edited June 24, 2014 by NuclearNarwhal Link to comment Share on other sites More sharing options...
GenPage Posted June 24, 2014 Author Share Posted June 24, 2014 Okay here is what you do: Next start the Java Preferences app from /Applications/Utilities drag Java 7 to the top of the list like in the screenshot. This will make locally run Java applications use Java 7 instead of Java 6. You can uncheck the Java 6 options if you do not want them to be allowed to run. This section is for the Java runtime for local applications, and has nothing to do with the web plugin. Link to comment Share on other sites More sharing options...

Is there any way to access it using the newer Mac OS X? Edited June 24, 2014 by NuclearNarwhal Link to comment Share on other sites More sharing options...

Torezu Posted February 17, 2015 Share Posted February 17, 2015 You need 64-bit, not 32-bit, Java. It should be available on Oracle's site. Link to comment Share on other sites More sharing options...
Firebyrd94 Posted July 6, 2016 Share Posted July 6, 2016 For the PC, i had to remove(uninstall) all instances of Java, then use the Windows Offline link in Oracles site to get the 64 bit version, also you may have to DL the 64 bit versions of any browser you use as well. the PCs should be able to have both 32 bit and 64 bit installed, but for some reason Tekkit launcher would only read 32.
