The JVM provides the environment necessary for code executions. The Java Virtual Machine is included in the Java Runtime Environment package because the JRE software uses the JVM to run compiled codes. To allow the Java Runtime Environment to run codes, the Java Development Kit includes debuggers that test and find errors in the written language as well as the Java Compiler to compile the codes. Both the JRE and JVM are located within the JDK along with development tools. The Java Development Kit is equipped with the mechanisms necessary to convert the Java source code into formats that the JRE and JVM can implement.
The Java Runtime Environment edition does not include the development tools that are needed to create Java programs. Two additional platforms that were created by Oracle are the Java Development Kit and the Java Virtual Machine: the JDK and JVM. Developed and released by Oracle, the freeware has been specifically created for Java content.
To run apps written in the Java programming language, people need to have the app version installed on their computer. Layered on top of operating systems, the JRE runs Java applications by supplying the class libraries and environment. It is compatible with Apple Mac, Linux, and Microsoft Windows electronics on both 32-bit and 64-bit operating systems. Use third party programs only as needed after a Windows utility fails or is insufficient for your task.Java Runtime Environment is a free program that lets people run Java computer software on their devices. Try to use the built-in Windows utilities as much as you can. I can't help but think that all of the third party programs you have been downloading and using to install/uninstall/defrag have contributed to these problems by not behaving as the Windows utilities would. If it is, run FTB launcher and see if it recognizes 64 bit java. If the install went correctly, open your Java control panel and verify that V7 u45 64 bit is installed. Make sure you let us know if the screenshot was after uninstalling everything or after installing the linked package.ĥ. Open another command prompt and type 'java -version'.
Now install the package I linked above.Ĥ. Windows doesn't see any installed Java versions. Come back here and tell us if the command worked (post a screenshot of the output if it doesn't fail).ģ. If this returns some info on Java, then something didn't uninstall correctly. This command SHOULD fail because all Java versions should be uninstalled. Uninstall all other Java versions using the Windows add/remove programs menu.Ģ. Select "windows Offline" and install it as follows:ġ. Try this link (manual download of 64 bit JRE 7 update 45):
