Gradebook error. "Could not call startup.startup"

Customer Question

I am getting the "Could not call startup.startup" error as well when I try opening Gradebook. I ran this command: sudo /usr/libexec/PlistBuddy -c "Delete :JavaWebComponentVersionMinimum" /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.meta.plist and still nothing. Please help.

Hello. My name is XXXXX XXXXX I'll do my best to help you with this problem. First let me ask where the command that you ran came from. It sounds like there was an initial problem that caused you to run that. So if you could elaborate on that, it would be helpful. Thanks!

I came across a similar problem reported from someone on this site, and the expert told them to run that script

Expert:  Expert Scott replied 3 years ago.
From what I can find, it sounds like a Java installation problem. My first suggestion is to update your version of Java. Please go to www.java.com and download and install the latest java plugin available. I would recommend you close all applications prior to updating Java as well. If after that it still does not work, make sure that your operating system is up to date as well by running "Software Update" from the apple menu in the upper left corner. Let me know if neither of those methods helps to solve the problem.
Customer: replied 3 years ago.

Both Java and operating system are up to date. Still no luck.

Would you please let me know what version operating system you are running? You can find that in the Apple menu and click About this Mac. Thanks.

I'm trying to get it to work on the macbook which is 10.8.5, but I also am trying it on my imac which is 10.9

I'm still digging around for a solid answer. However, this following instructions are what I found on the same issue. Since I don't have access to this application, can you take a look and see if these instructions guide you to an answer that works. In the meantime I'll keep looking to see what alternative there is to the problem. Looks like there might be some other possibilities.

"In PowerTeacher, click on Gradebook at the left. Under the Launch PowerTeacher Gradebook there is a warning line - "If the launch button failed to open PowerTeacher gradebook, click here to further assess the problem." Select the "click here" and it takes you to the directions."

Ok, followed those directions on both macs. On the 10.9, it said the file is damaged and can't be opened. On the 10.8.5, it popped up in the dock briefly and then disappeared.

Ok, this is similar to other reports I read about. Let me dig just a little more and I'll be back in touch in just a few. Thanks for your patience.

Okay. So from what I have found, Pearson has issued a statement to not update to Java 7 update 45. This breaks the application. However, one person said that they were able to get it to work by uninstalling that version and reinstalling a previous version. So here are some instructions on each step. Let me know if you have any questions or problems along the way.

First uninstall Java 7 using the instructions in the following link...
http://www.java.com/en/download/help/mac_uninstall_java.xml

Once uninstalled, download the following version and install it...
http://download.oracle.com/otn/java/jdk/7u40-b43/jre-7u40-macosx-x64.dmg

Last step is to make sure that Java does not automatically update and put you back in the same predicament.
  • Launch the Java Control Panel by clicking the Java icon under System Preferences.
  • Go to the Update tab in Java Control Panel and uncheck the box that says "Check for Updates Automatically"
  •  

    Now... Test it out and see if it works. Good luck.

    Ok I wasn't able to install the javascript from your second link because it needed me to agree to terms, but I did end up downloading javascript version 7u40 eventually, and unforunately, now I get a new error message from gradebook saying

    "Encountered connection error. Please contact your system administrator."

    I found this link from Pearson, but don't know if it has a solution because I don't have a login for this site. You can try it and see if you have access and let me know if there is anything helpful in there. Otherwise I will search the new error and get back to you. Sorry this is so troublesome. I see this a lot with applications that have Java dependencies. I'll be in touch later. Thanks for your patience.

    Has anything changed since your last reply? Are you still receiving the same connection error that you posted? Let me know and if you like, I can also setup a remote assistance connection so I can help you by running some diagnostics and possibly reconfiguring some items that may help. It's also possible that Pearson is nearing a fix for the latest Java client. I will check on that too.
