Unable to open ESR/ID PI 7.31

Hi everyone,

I've seen several topics with issues similar to this one but I have had no luck in resolving the issue so far.

As stated in the title, I can't open ESR and ID for PI 7.31.

To describe what's been happening, either one of two things happen after clicking the link to open ESR and ID:

a) I get an application error ending with "jnlp file truncated after 10K" then it further describes the error as a premature EOF because of "FailedDownloadException: Unable to load resource".

(see attachments for images)

or b) the jp2launcher.exe (or javaw.exe for 1.6) just stays on the list of processes without any progress or error message.

I'm currently running Java 1.7.0_71 but I've tried uninstalling 7 then switching to 1.6.0_45 without success.

I've also tried clearing the cache for both Java and the browser followed by restarting.

If it's any help, at one point I tried with a new PC running Java 1.6.0_45 and it was able to function. However, after the PC silently updated to 1.7, my issue returned.

Best Regards,

    Hi Charles,

    From your post it seems this issue is due to the Java version on your System.

    1. Uninstall 1.7 and Install 1.6.0_45

    2. Go to Start --> Control Panel --> Java

    3. In the Pop-Up, 1st Tab click Settings under Temp Internet Files and Delete Files

    4.Go to Update Tab and Uncheck Auto Updates Otion

    5. Go to Java Tab -- Both User and System and Ensure you have just 1 Java version 1.6.0_45 enabled in it (screenshot attached)

    Hope it helps

    • you can also try to start the ID and ESR with a command file. That way you do not have to delete your java 7, but install 6 (or 5)next to it. See example below

      @Echo OFF

      Goto :START

      *** Hi,

      *** Populate repOrDir with "rep", "dir", or "both".

      *** it's case INsensitive, so REP or Rep etc will do.


      set server= yourservername

      set domain= yourserverdomain

      set port= :51000

      set repOrDir= Both

      set javawsDir= "\Program Files (x86)\Java\jre1.5.0_22\bin"

      StartRepAndDir %server% %domain% %port% %repOrDir% %javawsDir%
