Java Jdk Latest Version For Windows 7 64 Bit
Kathryn Garivay
I immediately get an error telling me to install the proper version of Java. I looked up in the system reqs which states you need to have Java 1.8.0_92-b14 64 bit. i have Java 1.8.0_181-b13 and need this version for other installed software.
I just looked and my 64 bit Java in C;\Program Files is no longer there. I am wondering if my company did an auto update and removed my 64 bit Java install. It has happened before. Let me reinstall the 64 Bit version of Java then I will let you know.
Has anyone there looked at what is causing the failure? I assume it is because there are either files handing around that the install script is seeing or there are registry settings that are still set that need to be removed.
I am using the install guide that was referenced above (thanks tmousaw). It says to "obtain the Thingworx.war". When I click the link to PTC Software Downloads, I am told "Access Denied. Insufficient Privileges". I am running the install from the twxFoundationH2Trial-8.3.2-windows-installer.exe i downloaded previously. Is there another way to access the war file?
When I am using openJDK Java in one machine sandbox is working fine .
But when I am using SDK in the machine with java from oracle provider I am getting following error.
Caused by: java.lang.UnsupportedClassVersionError: com/github/blemale/scaffeine/CacheLoaderAdapter has been compiled by a more
recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
The question is not whether or not do you have java.exe installed, it is whether or not do you have a system managed version of it in your C:\WINDOWS\System32. If you do, that takes over the precedence whenever you run the daml assistant and it calls out to execute jars, but does not do when you execute from your interactive session.
Installing multiple Java versions in parallel is incredibly easy in Windows. You can download and run the installer for each version, which automatically installs the versions in separate directories.
These variables should always point to the same Java installation to avoid inconsistencies. Some programs, such as Eclipse, define the Java version in a separate configuration file (for Eclipse, for example, this is the entry "-vm" in the eclipse.ini file).
The scripts update the JAVA_HOME environment variable and insert the bin directory at the beginning of the Path variable. That makes it the first directory to be searched for the corresponding executable when you run Java commands such as java or javac.
If you have installed the latest releases of all Java versions, you can use the scripts without any further adjustments. Open a new command line or PowerShell and enter, for instance, the following commands:
If one of the commands does not activate the expected Java version, please check if the path in the javaX.bat and javaX.ps1 files corresponds to the installation path of the Java version you want to activate.
The commands presented up to this point only affect the currently opened command line or PowerShell. As soon as you open another command line, the default version defined in step 2 is active again (Java 22, if you have not changed anything).
Attention: To set the Java version permanently, you must open the command line or PowerShell as an administrator. Otherwise, you will get the error message "ERROR: Access to the registry path is denied.
I did this and now I can use command prompts to switch between versions as verified with "java -version" BUT I still cannot get my browser based interface to function correctly on the version 6. It DOES function correctly if I uninstall all Javas and reinstall just 6. Does this method not work for browser based applications?
Hi Daniel, the scripts from the first version of this article worked only in the command line, in which you executed them. The latest version of the article now contains additional scripts to change the user and system defaults (see chapter "Temporary, Permanent and System-Wide Java Version Changes").
Or are you speaking of Java applets? Support for applets has been removed with Java 11, and I haven't worked with them in years, so I don't know if there's a way to change the Java version used for applets.
I had to move the %JAVA_HOME%\bin to the first option in the PATH as before when it was last in the list of values, when I ran java -version in cmd, it reported java 1.8 instead of java 1.6 which did show when I ran: echo %JAVA_HOME%
UPDATE: I have uploaded a new version of the scripts. Instead of "javaversion-user" and "javaversion-system" you now have to call "javaversion perm" to change the version permanently (see section "Temporary and Permanent Java Version Changes"). The new version is also more reliable than the old one.
Hello everyone.
First of all thanks for the script.
In my case the change of jdk worked but each time a new terminal was launched the default jdk came back ...
As a result, I modified the script so that now with each change, the jdk selected by script is 'saved'. You have to add the REG (be careful , only in one line) line as below by adapting the right path of the jdk to your configuration:
I've tried with this :
REG ADD "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment" undefined v "JAVA_HOME" undefined t "REG_SZ" undefined d "C:\Program Files\OpenJDK\openjdk-8u262-b10\" undefined f
But the commande is not working. do you see something wrong here ?
I didn't set it up on the Windows 10 Server but I think that when it starts as a service using Tomcat9.exe it is ignoring the environment variable and using the -auto option to locate the JVM in the registry. I am not a Windows aficionado so I am not sure what the registry key would be and there are only about 1500 of them.
This has been one of the most fruitful topics I have read and implemented in a long time. This problem of working on multiple Java versions simultaneously has been haunting me for a long time. The solution provided is cute, simple and it is going to save several hours of misery for me. Thanks
nice solution for switching versions, i was trying to merge all the version scripts in one bat file but and added a if else statement i am not able to run that bat file by default in my command prompt. Any idea
I'm trying to switch between Java 8 and Java 16. In the terminal I use the commands in ("java8"/"java16"), it confirms that my version has been switched, but as soon as I close and open a new terminal, it is still the version I tried to switch off of. I have very little experience with this stuff, and any help would be greatly appreciated.
Hi Chase, you can use the recently added commands "java8-user" and "java16-user" (for example) to set the Java version permanently for your user account (see the newly added section "Temporary, Permanent and System-Wide Java Version Changes").
UPDATE: I have uploaded a new version of the scripts. Instead of "javaversion-user" and "javaversion-system" you now have to call "javaversion perm" to change the version permanently (see section "Temporary and Permanent Java Version Changes").
This is fine, however, the script doesn't work properly with -user suffix, given, my computer seems to be special in how it does things. The user variable Path has one value, and it goes to %USERPROFILE%\AppData\Local\Microsoft\WindowsApps
If there is a better value or values for it, please respond with such or at least one for JAVA_HOME variable for User to work.
Hi Evalyne, I have uploaded a new version of the scripts. Instead of "javaversion-user" and "javaversion-system" you now have to call "javaversion perm" to change the version permanently (see section "Temporary and Permanent Java Version Changes"). The new version is more reliable than the old one, let me know if it works for you.
Nice work, I did one change though I merged them all into one and used the %1 %2 to indicate the version I was interested in running and if I wanted it user or system besides that excellent work. Thanks for taking the time to make the tutorial.
To fix this you'll need to remove the entry C:\Program Files (x86)\Common Files\Oracle\Java\javapath from PATH and make sure you have %JAVA_HOME%\bin entry under PATH and corresponding JAVA_HOME defined.
hi mam this is a real help as a minecraft dev I am still coding in 1.17.1 and was planning to shift on 1.18 but both have a different jdk and thanks to you no i can switch between jdk version and use spigot
Appreciate the article, I was having issues running a modded Minecraft server as mods can be picky about the java version there run on and was looking for a quick and simple solution just like this one, was extremely simple and easy to follow
This is one of the few posts ive seen that both provides a great description for how to set up java, as well as the easiest way ive seen to switch java versions on the fly.
10/10 would recommend to my whole company (already have ;))
I'd suggest to modify the scripts in a way, that the paths are set in one file only. I realized that a lot of work is involved if you want to install to another location and each and every script file had to be adapted.
I have updated the scripts in a way, that the javaN.bat/javaN-user.bat/javaN-system.bat have basically just have one line that redirects to a generic script that does everything the original script does, but using the version as a parameter. To combine them further, I used another script to set JAVA_HOME based on the parameter, so that all the version-path-mappings are enclosed in this one file.
