How to degrade java 8 and install java 7
With the new forge build 1345 there is no need to degrade to java 7 for MC 1.6.4 mods!
Forge build 965 and lower wont run with the new java 8, so you must degrade to java 7 if not done yet.
- First you need to uninstall your current java. This step is important you must do this!
- Go into your Control Panel
- Open Programs and Features
- Search java, click on it and uninstall.
- Then Download java 7 from here: https://www.oracle.com/java/technologies/javase/javase7-archive-downloads.html
- Accept the agreement
- Download the java your system requires
- And simply run it and follow the installers instructions.
If its still not running then you will need to edit your Profile in the Launcher.
- Open a New Profile Or Edit your Profile (depends on how you use it)
- If you open a New Profile give a name first. If you Edit Profile you may skip this step.
- Select a minecraft version at ‘Use version’, you will probably use ‘release 1.6.4-Forge184.108.40.206.965’
- The Important part check ‘Executable’ at ‘Java Settings (Advanced)’ and type in your Java 7 path. It can be:
- “C:\Program Files\Java\jre7\bin\javaw.exe” If you type it in the Start Menu search field it should give you that exe file if it correct but don’t need to open that file!
- “C:\Program Files (x86)\Java\jre7\bin\javaw.exe” If you type it in the Start Menu search field it should give you that exe file if it correct but don’t need to open that file!
- If the Java executable is found and the above steps are completed then you can ‘Save Profile’ and start Play to see if it works.
