Java 8 Update 201 Download 64-bit
Jacque Waiden
I'm working on a web site project with a Java component and am currently testing for cross-browser compatibility. Most is fine but the Java part won't load on 64-bit browsers. Looks like I need a 64-bit JRE to test. Where does one download the (off-line) 64-bit Java runtime installer for Windows?
Yes to the first question and no to the second question; it's a virtual machine. Your problems are probably related to unspecified changes in library implementation between versions. Although it could be, say, a race condition.
There are some hoops the VM has to go through. Notably references are treated in class files as if they took the same space as ints on the stack. double and long take up two reference slots. For instance fields, there's some rearrangement the VM usually goes through anyway. This is all done (relatively) transparently.
Also some 64-bit JVMs use "compressed oops". Because data is aligned to around every 8 or 16 bytes, three or four bits of the address are useless (although a "mark" bit may be stolen for some algorithms). This allows 32-bit address data (therefore using half as much bandwidth, and therefore faster) to use heap sizes of 35- or 36-bits on a 64-bit platform.
The Java JNI requires OS libraries of the same "bittiness" as the JVM. If you attempt to build something that depends, for example, on IESHIMS.DLL (lives in %ProgramFiles%\Internet Explorer) you need to take the 32bit version when your JVM is 32bit, the 64bit version when your JVM is 64bit. Likewise for other platforms.
"If you compile your code on an 32 Bit Machine, your code should only run on an 32 Bit Processor. If you want to run your code on an 64 Bit JVM you have to compile your class Files on an 64 Bit Machine using an 64-Bit JDK."
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.
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.
Update: it seems that the actual (at the time of this edit) version of 64-bit Pi OS is getting packages from Beware that on a 32-bit Pi OS, adding Debian repo as a source and doing an upgrade is known to ruin the system (at least it was the case last time I tried).
I feel like this should just naturally work, but for some reason it isn't. I've gone through the following guideHow can I install Sun/Oracle's proprietary Java JDK 6/7/8 or JRE?And it seems that all the help isn't working.
So as you see, the file is there, but also not there at the same time. Which is hyper confusing. I next thought that maybe I didn't actually have a 64-bit version of Ubuntu, but I checked and (if I'm reading everything correctly) it looks like I do have 64-bit ubuntu:
I use the following code to remove all versions of Java before installing the new 64-bit updates. Note the line continuation characters following each pipe, in the attempt to make the code more readable.
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).
I though this was a Windows 11 problem but after trying on my old Windows 10 PC I get the same error. Sorry for the re-post, I thought it was a Windows 11 issue.
Due to a hard disk crash I have to re-install Line6 Edit for my good old Pod 2.0. But the installer depends on being able to download and create jre_setup.exe for Java Runtime v1.6 32-bit and that download fails. Being fully aware of the security issues with outdated Java installs, what are my options?
I'm surprised Windows11 even works with a 32-bit computer. Are you sure you have a 32-bit version of Windows 11? Go to Windows - Settings - OS Build Info. Under Device Specifications - System Type - Does it say 32-bit or 64-bit? My Windows10 64-bit computer runs Line6 Edit fine. Also why does the Java download fail? Is there an error message?
It's not the computer that is 32 bit but rather that the line6 editor is trying to download it. The computer is a new i9 Windows 11 x64.
If you look where the app is installed, it's installed in C:\Program Files (x86)\Line6\ which is used for 32-bit architecture.
When installing it flashes a warning saying it needs the runtime, attempts to download it with a "Connecting" message then fails with another error message with no specifics given. When you run the app, it then gives you the message, "This application requires a 32-bit Java Runtime environment 1.6.0". It sends you to the JRE download but only 64-bit is available, I believe as I cannot find any 32-bit versions on the Java site. Only options appear to be on online file archives and they make me nervous, even though I have BitDefender.
Same error for Windows 10. So, if for any reason you lose your Line 6 edit installation (as I did) you can't reinstall.
Problem solved although I'm not crazy about having old Java on my PC.
I found the Java archives and figured out what appears to be the last version to support 32-bit Java (indicated by windows-i586 in the name, I guess named after Intel Pentiums): -later-archive-downloads.html
This requires that you create an Oracle account. You have to be sure you are signed in when you are on the link above or the download won't work so check the "Accounts" icon in the top right if you have trouble..
I downloaded and ran the file jre-8u311-windows-i586.exe and this time when I ran Line 6 edit, it ran as expected and connected to my Pod 2. and I am back in business! I hope this helps someone!

This may or may not be something in which I'm interested at some point, but I heartily commend and thank you for following up and presenting the solution to the problem that you encountered. Wish everyone were so helpful and considerate!
Hey everyone, I need to use Java 64-bit in Mac OS X Lion and I thought it defaulted to using the 64-bit JDK until I ran Minecraft which stated I was running the 32-bit JDK and if I deselect the 32-bit entry in Java Preferences it deselects the 64-bit entry as well. Does anyone know of a way to make OS X default to the 64-bit version, I also make use of the 64-bit JDK on Windows to ensure my Java applications in NetBeans run correctly on either flavour.
I did try using the OpenJDK 7 and downloaded the 64-bit runtime and installed it correctly and confirmed it was running but when running the Minecraft.app I was greeted with a message saying no compatible JDK 1.5+ was installed and when using the Terminal, it was failing to logon correctly, but was working fine in the standard JDK but like I said, I'm stuck with 32-bit in that case.
There isn't really a default java, but you can set the order for your preferred java. Go to the Java Preferences (/Applications/Utilities/Java Preferences) and on the General tab just make sure the 64-bit java is first (you can click and drag them to change the order).
