      This problem is due to having Java 32 bit installed, k.Modeler needs the 64 bit version.  The red circle in the image above indicates that the wrong Java executable has been installed.

      The process of having multiple version of Java in the same computer can be complicated and requires more advanced knowledge of path configuration.  If you do not need multiple versions of Java it is best to uninstall all other version and install the JDK 8 64 bit version for your operating system.

        i install java 64-bits to my pc but i I still keep getting the error. how to fix it?


        1. Enrico Girotto

          Good morning.

          This answer is from 2020, now the system works in a different way and it is still not necessary to download a specific Java version.

          Can you explain what's your issue?

          If possible, please include a screenshot of the error.

          Thank you, Enrico. I get the error Input/output error: java.lang.IllegalArgumentException: No enum constant org.integratedmodelling.klab.api.provenance.IArtifact.Type.ANNOTATION when installing k.LAB on windows. I have examined the files, they are incorrect or incomplete. I read your email and tried to download it again. But the problem remains. As a solution, I installed the program on Kali Linux. but I'm having a hard time working. That's why I find it more convenient to install it on my Windows computer. I think this error may be due to the old version (ie Windows 7-8). Thank you for helping.

          ANNOTATİON 'İ' error. ? 


        4. Enrico Girotto

          Good morning Tuba,

          These errors are usually due to an incorrect download or an operating system issue.
          The system hasn't been tested on Windows 7/8, so you may experience problems.
          Please email support@integratedmodelling.org with your system configuration and details of the error you're experiencing.

          Hello, as you said, I reported the problems I encountered in the installation of the k.LAB control center to support@integratedmodelling.org. I also sent the screen shots. Thank you for the solutions you offered.

        I got the exact same problem, however, the k.Modeler was working fine before. 

        I checked and I only have one version of Java installed, which presumably should be the 64 bits one, as it is the one I downloaded and the k.Modeler was using to operate before.

        Could it be that the Java would switch itself to the 32 bits version, or this does not make any sense?

        Do I need to reinstall Java to fix this issue? or there is another solution? 

        Thanks!

          Hi, can you post a screenshot of the error starting the k.Modeler?
          It seems that you have the correct java version, but to ensure that, please post the result of doing this:

          • Go to the command prompt (click on windows menu button and write `cmd`
          • Type "java -version" and press enter
          • Copy or make a screenshot of the result

          Thank you for your prompt response Enrico,

          Here is the screenshot of the command prompt and the k.Modeler error (code=13). The mysterious part as I stated before is that the k.Modeler was working fine, and one day I tried to open it, and that error came up.  

           


          Muchas gracias!

          Hi Geronimo,

          you are try to run the k.Modeler using the 32-bits version of Java
          if you had the 64 bits version, it would look like this

          In Windows is possible to switch between JVM if you have both installed doing this:

          • Open Control Panel, select Java
          • Change to tab Java and press View... (I have it in Spanish, so the button could be different)
          • In this window you can see which java you have and select the one that windows must use
            The x86_64 Arquitecture indicates the 64 bit version

          If you don't have a 64 bit version installed, you can download Windows x64 version from here
          https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html (To download it you need to create en Oracle account)
          Once installed, repeat the previous procedure and select the x86_64 version.

          Hope this help

          Enrico, 

          I tried what you mention, and apparently I had the correct version.

          However, I downloaded the newest version of the Java from the link you shared and that fixed the problem. 

          Thank you very much for your help!
