Java Version 64 Bits
Ingelore Clason
I am having the same issue. I have never had 32-bit Java in my life and when I look up what Java version, it still says I have 64-bit, but Technic launcher says I only have 32-bit therefore I only get 1 Gb of ram. Please help!
I tried the above solution, I've checked the command prompt to see if I have any additional instances of Java installed, I've manually scoured through my files to make sure... I definitely only have 64-bit Java installed and yet Technic refuses to recognize it. Any helpful hints would be greatly appreciated.
for anyone coming to all these years-old threads looking to fix this problem, what helped me is updating whatever version of java i'm using WITHOUT uninstalling the previous version that technic was recognizing, opening the technic launcher, navigating to launcher options and changing which version of java to use. from here i was able to change my ram from 1gb to 4gb perfectly fine.
i have never had java 32bit installed. for whatever reason the technic launcher ran just fine with my 8.231 version of java 64bit, but upgrading to 8.381 made it unable to run. many people in other threads here and on reddit said to uninstall the previous version and keep the latest version, but the only thing that worked for me was having both versions and just switching which version to use within the technic launcher.
Then regarding 32 bits or 64 bits version, I think it should be 64bits. Try to install it please. I think to remember that on old servers I got the 2 libraries 32 and 64 bits installed, but with newer Adobe Campaign version it was a 64 bits runtime and the JDK 64 bits is enough.
However I notice your AC version is 32 bits so I wonder why.
On Windows it seems the nlserver is purely using registry key when trying to locate JVM on the disk. It is not using JAVA_HOME, PATH or any other method you may be used from other Java process launchers.
Specifially nlserver looks in registry location HKLM\Software\JavaSoft in order to find a JVM. Setting this registry key is not part of the Java standard; it was/is a proprietary thingy done by Oracle's Java installer. The consequence is that if you use any other Java distribution than Oracle's (or haven't installed the JDK but just unpacked a ZIP bundle) then you need to double-check if your specific Java distribution sets this key or not. If you are using AdoptOpenJDK, Zulu, Amazon Corretto or any other Java distribution which is not Oracle's then you need to verify the presence of this registry key.
I wanted to run java programs on a 64 bit Windows 7 computer and I have a 64 bit Java VM. How do I launch the jar files via command line ? It seems that 64 bit Windows 7 have a seperation between 32 bits and 64 bits programs.
Some jar files have information in them allowing to be executed with the -jar switch. If that information is not present you must use the -cp myjar.jar my.main.method.class argument to java.exe to execute your program.
So, do I really need a 32-bit Java version next to my 64-bit Java version? Is that even possible? Do I need to set up something else? I need the 64-bit version for other apps, I cannot replace it with a 32-bit version (provided that's even possible with 64-bit Win 7).
And I didn't even have to change JAVA_HOME to get the data loader working, it just works now. Automagically. Not even PATH was changed by the installer. java -version still reports the 64-bit version, but somehow data loader can find the 32-bit version (I guess because it was installed in its default folder).
For the IoT Gateway to run, KEPServerEX requires a working 32-bit Java JRE or full JDK installation version 7 or higher. At this time, a 64-bit JRE or JDK is not supported. I Just wanted to know if we can use AdoptOpenJRE instead of 32-bit java JRE?
When you have installed a 64-bit LibreOffice, and 32-bit JRE, LibreOffice would not be able to find and use the JRE, no matter how hard you would try it. Take care that you download from the Java home page (www.java.com) the right architecture. In this case, LibreOffice (of reasonably fresh version) would try to be helpful in its "JRE Required" error message, telling you that it needs specific architecture (e.g., 64-bit) of JRE.
Launching Java Control Panel ("Configure Java" available in Windows Start menu), and clicking "View" button on "Java" tab, opens Java Runtime Environment Settings window with Architecture column allowing to see if installed instances are 32-bit (x86) or 64-bit (x86_64).
On macOS 10.10 and newer, please note that you need to install JDK, not JRE. You may find download links choosing JDK version on this page. Note that Apple M1 is an Arm 64 architecture.On macOS 10.09, neither JRE, nor JDK are found.LibreOffice releases available from Apple App Store don't include Java support at all, because apps distributed in the App Store are not allowed to depend on optional functionality like Java.
Installing Eclipse is relatively easy, but does involve a few steps and software from at least two different sources. Eclipse is a Java-based application and, as such, requires a Java Runtime Environment or Java Development Kit (JRE or JDK) in order to run.
Regardless of your operating system, you will need to install some Java virtual machine (JVM). You may either install a Java Runtime Environment (JRE), or a Java Development Kit (JDK), depending on what you want to do with Eclipse. If you intend to use Eclipse for Java development, then you should install a JDK. If you aren't planning to use Eclipse for Java development and want to save some disk space, install a JRE.
A Java 17 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2023-06 packages based on Eclipse 4.28, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
A Java 17 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2023-03 packages based on Eclipse 4.27, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
A Java 17 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2022-12 packages based on Eclipse 4.26, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
A Java 17 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2022-09 packages based on Eclipse 4.25, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
A Java 11 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2022-06 packages based on Eclipse 4.24, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
A Java 11 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2022-03 packages based on Eclipse 4.23, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.
There are several package choices. Note that you can install the features from any package into any other package. If you are, for example, planning to do mostly Java development and some C/C++ development, you should download the Eclipse IDE for Java Developers and then add the C/C++ development tools via the "Help > Install New Software..." menu option.
The download will be delivered as a compressed (i.e. a ".zip", or ".tar.gz") file. Decompress this file into the directory of your choice (e.g. "c:\eclipse" on Windows) and ensure you have full Read and Execute permissions. You can optionally create a shortcut of the executable file ("eclipse.exe" on Windows, or "eclipse" on Linux).
Note that there is a known problem with the built-in decompression utility on all current versions of Windows. We recommend that you use a more robust decompression utility such as the open source 7zip when decompressing an Eclipse download. Some people report success when initially decompressing Eclipse into a root directory (e.g. c:\) and then moving it to a more appropriate home (e.g. c:\Program Files\Eclipse)
It is strongly recommended to configure Eclipse with the specific JVM that you want. See the instructions at Eclipse.iniThis is a very important step to be sure that Eclipse is using the JVM you intend and can't be influenced by any other software that might alter your system.The JVM used to launch Eclipse has no affect on whether it can compile Java sources for other Java language versions.
Use the Help > Install new software... menu option to add Kepler features to your Eclipse installation (you can, for example, use this option to add C/C++ development support). Additionally, you can tap into a vast collection of extensions provided by the Eclipse community and ecosystem via the Eclipse Marketplace Client (Help > Eclipse Marketplace). Note that not all Eclipse packages contain the Eclipse Marketplace Client.
