    This is no help but just to let you know it is happening for us too.
    Admins go through same filter as staff and it is running for admins but not staff!

    Hi

    Same issue here with our school (we use a Sonicwall E5500 / Impero for content filtering.) Initally I thought it was a permissions issue (Domainadmins work, student/teachers do not)

    Will turn each one of these off to test and feedback if it helps.

    Wil

    Ps anyone know any good alternative to MIT apps as a Plan B ?

    Try a different version of java.
    We had similar error using IcedTea wirth Open JDK but using Oracle 7 worked ok.

    Also, this is what the Java debug console logs:

    Trying to download phone app apk

    Phone app apk saved into temp file: C:\Users\USER~1.DOM\AppData\Local\Temp\aia33382419 01795979705.apk
    systemId is file:///C:/Users/USER.DOMAIN/Desktop/ignore_lang_def.dtd publicId is null

    Reading language definition DTD from jar resources.
    Preparing phone for new project
    Creating GUI...
    ==== Loading form, project is test_copy
    No zip file from server. Returning empty file map.
    And then nothing happens.

    are you running a local build server?

    No, we are not running a local build server.
    We are running Java 6, also tried Java 7 with the same results. Yes we have installed the android emulator software but it has made no difference

    Bump....

    I have been asked to install this, also on CC4 but runs as staff and Admin but not as a student. All users use same internet settings/connection.

    Any help would be great, I have logged a call with RM too.

    I found out that students are blocked from running scripts by default on CC4 - Enable this in the RMMC and it works BUT we are not going to do this as it's too much of a security risk.

    The only way I could see to get this to work on a CC4 network for students was to remove the station security!

    We have had the same issue.

    The problem we had is that command prompt script processing was set to "Yes" we changed this to "No" and it works!

    Not sure of the security implications though!
