    JAVA and Windows 8


    Hi, I am having a similar issue with JAVA and Windows 8 running in desktop mode.
    After downloading the recent JAVA update 51, I lost connectivity. According to my IT department at work (I work remotely) it was a fluke that I was able to connect with Windows 8 at all. I have tried Firefox, Chrome and IE.

    Can I install a second OS on my laptop to connect to my work website with JAVA? I had issues with my school websites that their IT department had been able to help me correct, so it is not that JAVA is not installed, it's just that JAVA and Windows 8 apparently don't always play nicely together.

    Any suggestions on fixing this issue?

    If you have older OS discs you could try VMWare Player, it is a good virtual machine . You can also set up a dual boot system, that is more complicated.

    Here is tutorial on dual boot: Dual Boot Installation - Windows 8 and Windows 7 or Vista

    Here's the solution:

    1. Uninstall previous versions of Java.

    2. Download the setup file from the home page. Offline or Online setup file does not matter. But if you want x64 version of Java, you need the Offline setup file.

    3. Install Java.

    4. Get Java verified as follows:

    Open this page to get Java verified: Verify Java Version

    - Chrome: Open that page to verify Java.
    - FF or IE: First of all, run these browsers as Admin, and then open that page to get it verified.


    If you open a page and got this message: Application blocked by security settings.

    Just search for the shortcut "Configuration Java" in C:\ProgramData\....

    Open it, click on Security tab, click on Edit Site List ..., add the page on which Java is blocked and click OK.

    Now reload the page and you'll see a message asking if you wanna to run Java, just click Run.


    There we go!



    P/S: This works on Windows 8.1.

    This looks like an ancient thread, but I will try anyway. Java is embedded in Windows 8. It shows up in Control Panel. It does not work on all websites. I cannot uninstall and reinstall. I cannot install from any website that tells me I need it. It does not work from my Start either, even though Java help says it will. It will not work with Google Chrome. I downloaded Firefox and got great amounts of malaware and a virus, so I don't want to try that again. (It took Dell Tech 2 hours to clean up my PC). Perhaps someone that sees this may have a solution that overcomes the above restraints.

    Java Verify failure unable to Configure Java Control Panel does not open ( Fix : )
    this is a regular ( windows 7 bug related ) problem after successful installation of Java ( jre ) and fresh installation of Windows7 64bit or 32bit on my laptop or desktop. what worked perfectly for me was setting COMPATIBILITYMODE=WINDOWSNT to make windows launch the JP2LAUNCHER.EXE and JAVAW.EXE files properly.
    jp2launcher.exe windowsNT compatibilty solves Java Verify failure problem at https://www.java.com/en/download/installed.jsp
    javaw.exe windowsNT compatibilty solves unable to open or Configure Java Control Panel problem.


    * search for JAVAW.EXE inside c:\program files\java\....\bin
    or c:\program files(x86)\java\.....\bin\
    * right-click mouse on JAVAW application icon logo
    * click PROPERTIES
    * click COMPATIBILITY
    * tick the checkbox at COMPATIBILITY MODE
    * choose WINDOWS NT service pack
    * click APPLY or click OK
    Now, the Configure Java Control Panel will start opening and working.




    * search for JP2LAUNCHER.EXE inside c:\program files\java\....\bin
    or c:\program files(x86)\java\.....\bin\
    * right-click mouse on JP2LAUNCHER
    * click PROPERTIES
    * click COMPATIBILITY
    * tick the checkbox at COMPATIBILITY MODE
    * choose WINDOWS NT service pack
    * click APPLY or click OK
    Now, the Verify Java will be successful at https://www.java.com/en/download/installed.jsp




    if we find 2 or 3 versions of JP2LAUNCHER and JAVAW when we search, then we must repeat the above for all of them.




    in the Configure Java Control Panel Advanced tab we can set "Do not check" certificate revocation and disable security verification. and in the Security tab we may Edit Site List... for the Exception Site List ( add URLs to unblock sites )
