JRE Download

Thr JRE, Java Runtime Environment, contains a Java Virtual Machine, class libraries and other files that are needed to execute Java programs on a computer system. It has been designed for end users systems as it does not contain tools to develop Java applications like the Java JDK.

It basically boils down to this: If you want to execute Java programs you need the JRE. It does not really matter here if the Java program is executed in a web browser or locally on the computer system as both need the JRE to be installed. The Java Runtime Environment is often referred to by users as Java, Java Virtual Machine or Java VM which is technically not correct.

JRE Download refers to the download of said Runtime environment. Computer users have several options to download and verify the Java Runtime Environment which we would like to address in the following paragraphs.

JRE Downloads

Sun, which recently has been bought by Oracle, is providing free downloads of the Java Runtime Environment on their website. The easiest way to find the most recent version of the JRE is to visit this redirecting link on Java.com. The JSP script will automatically detect the web browser and operating system and load the right download for the user.

The latest version of the JRE is currently Java 6 Update 20. The Runtime Environment gets regular updates which means that this version will go up in the future.

Another option to download Java is to open the download page for all operating systems instead. The user needs to select the right operating system on that page and install the JRE manually after downloading the installer to the local computer system.

Windows users can download an offline or online installer. We suggest to download the offline installer as it contains all the files needed to install Java right away while the online installer downloads components from the web after the initial download.

Java will be added as a plugin to installed web browsers and available in the desktop environment to execute Java programs. The installation will also add the Java Quick Starter (jqs.exe) to the startup programs. You might want to consult the article above for more information on JQS.exe and why it might be a good idea to remove it from the startup programs list.

Verify that the JRE is installed

It is now time to verify that the JRE is properly installed after downloading and installing it on the computer system. This can be done on the Verify Java Version page at the Java website. Just visit that website and click the Verify Java version button.

verify java

The next page will execute a small Java program that detects the current version of the Java Runtime Environment that is installed on the computer system.

The page links to the Java download page in case an older version was detected.

Troubleshooting Java

Things can go wrong sometimes. The best approach in our experience is to completely wipe Java from the computer system to install it anew to ensure that no old files are still present on the computer.

This can be done manually or by using the software program Java Ra which provides the means to remove older Java versions from the computer system.

Computer users who have Java installed might want to start with the verification first to see if their JRE version is the latest available one. JRE downloads are also available on many download portals in case the Java website is temporarily not accessible.

    @Martin Brinkmann: with all due respect, this is now such a basic function, esp. for people reading your articles, that this article is like explaining to the readers how to calculate 1+1.

      Yes, I have to agree with this. I can’t imagine that there are many spreadsheet users who are computer literate enough to even casually read ghacks, but don’t know how to use a SUM function.

      Ever thought that people might google it so this artice might show up in the search results. So..no it’s not useless. I think it’s a good strategy explaining stuff even if it’s just basic things. Every day there is a new user on the internet searching for this kind of tutorial.

        @Malte: you make a good point, in principle. Nevertheless, nowadays telling people how to do a sum calculation, the simplest of the simple, in a spreadsheet is like teaching grandma to suck eggs.

        If say an elderly person would be sitting in front of a spreadsheet wondering how to sum a number of cells, that person is unlikely to look it up on internet, but would ask one of her/his children.

        And in any case, Ghacks is not a spreadsheet tricks and tips site, so it would not show up high in the ranking in a Google search.

        I`m an elderly person. 71.
        My experience in computers spans 50 years, focused on Unix internals, advanced degrees.
        I look to the internet for answers, since my children hate me and wouldnt tell me “jack”, even if they knew the answer.
        I dont know how to “suck eggs in principle”, or anything else for that matter. I’m retired and not interested in learning. Some other guy learned “the theory of sucking things.”

        Never needed spreadsheets, always too darn busy. Thanks for this info. Now I know how to sum two cells.

        Everyone starts somewhere.

        I am an elderly person and I can use sum, sumif, sumifs and so on. My kids come to me for knowledge on how to use excel and other programs ;)

        But then, I was in IT my entire career before I retired :)

        There are basic sites, and there are advanced sites. GHacks used to be more for people with technical knowledge. You can’t be everything to everyone though that seems to be the trend these days. Since it’s all about clicks and click bait the wider the topics the more you can remain “relevant”…

        However, that mentality tends to alienate the more technical people. I find myself spending less time here every month. It won’t be long before I stop coming here altogether.

        I have no mobile or wireless technology.

        Anything google or apple is insidious to me. And that accounts now for most of the content here.

        As to this article. Avast, and all of their products are untrustworthy. There has been much controversy and negativity regarding their products. I would think a reputable site would be more careful in what they publish… err, sorry, advertise.

      @Klaas Vaak: In Martin’s defense, it’s the day after Christmas, and some eggnog recipes pack a *real wallop*. Maybe we’re lucky he could type at all. ;-) More seriously, I don’t use Calc super-often, I typically type in the =SUM() function manually, and I’d actually *forgotten* where the Σ button is located in Calc. (The last time I was a heavy spreadsheet user, it was in an older version of Excel and I’m pretty sure the Σ button was somewhere on one of the “regular” toolbars.) So, the article actually did have a small payoff for me. Plus, there might be other intermediate or advanced users of other types of programs (graphics, audio, video, word-processing) who have never used a spreadsheet in their lives. It’s kind of hard to imagine, I know, but it’s possible.

    Overall LO has become a good SW, what prevents me to use it is:

    “it will not store the information about the data source once the data is imported”
    Until that functionality is implemented I’m forced to use M$ Office (2003).

    Yes, I use functions in Calc: Average, Min and Max. I use the mouse to select the cells.
    I don’t usually have to use Sum.
    Thanks for the info, and could we have more tips for LibreOffice?
    I find that the documentation does not keep up with the changes in LibreOffice.
    Also, it is hard to find info in the help documentation.

      @ShintoPlasm: yes, it is Martin’s blog, but it is a public blog with a comments section, which means he invites people to comment. And having been an avid reader for several years now, I am pretty sure Martin does not expect commenters to agree with him all the time.

      You do not help him with agreeing with everything willy-nilly and “honouring” him with praise. Martin, like everyone else in the world, is not perfect, therefore he can only learn from constructive criticism.

      Unfortunately you look at constructive criticism as a complaint. I do not agree with you on that and will keep making constructive criticism because I believe in keeping this website one of the best ones – refraining from constructive criticism won’t do that.

      Instead of being snarky, maybe you could be helpful. I’d like to add two numbers in a cell;
      In Excel, it would be
      =5+6

      I try that in this piece of crap software, and get a message “Invalid value.”

    I used Excel a lot when I was working. Retired now seven years. Excel was great, especially for macros. I now use LibreOffice, which works similarly but the macros are difficult in comparrison to Excel. I couldn’t find anything on macros for Free Office, which was disappointing, so I uninstalled it. I find Zoho to be the most similar to Excel but there you’re stuck with your spreadsheets in the cloud which I didn’t like.

      I was going to amuse myself and check out the comments for this Avast AV sponsored post since there were so many comments. I thought it funny since they have an article bashing the product in 2019.

      What do I see when I go to the comments? Ghacks pulled an “Amazon” and replaced an article on Excel SUM functions with a sponsored post to make it look like a good article.

      Anyone and everyone who even has a clue about tech knows that Avast is utter garbage and focuses on spying on you and spamming you with ads these days. Just check out the bad article from 2019 on this very site! If you run Windows 10/11, you already have better antivirus than Avast built-in to Windows.

    “HarmonyOS is open-source, which means that it can be customized by developers and manufacturers.”

    Both are quotes from the article. So which one is it, open source or proprietary?

      You trust Microsoft Windows, Google Android and Apple operating systems just because they are from businesses in your country ? Talk about blind nationalism.

      Do not forget also that there is a world outside of USA and that for most of human beings, your favorite operating systems are also of a foreign origin, and as hostile towards them as they are towards yourself.

    It won’t run programs or real games, so it will be useless.
    I mean, there are some people who apparently love using tablets and phones for everything, but mostly are people who will barely do anything with their brain in life.

    I mean, even if Photoshop, and others are available for iPad, do people think iPad is a threat for windows? not really, maybe for useless consumers who will just, like with a phone, be happy and move on, but not for professional industries which are the ones who matter the most, because are the ones who generate more revenue, since they buy the most expensive hardware and software.
    Nothing consumer computing related really makes much money, unless it is data from users that get sold for AI or Ads.

    Who knows where this comment is going to wind up. It’s in response to the article about Huawei’s HarmonyOS (HOS) operating system.

    Two places in the article it says HOS is open-source. One place the article says HOS is proprietary. Uh, I’m pretty sure it can’t be both. Which is it? If there’s some fine distinction, somebody needs to explain it.
