Troubleshooting: Launching PowerTeacher Gradebook opens a text file instead of the Gradebook


Q: When I launch PowerTeacher Gradebook my machine opens a text file instead of the Gradebook. Why?
A: On a handful of Mac OS X machines, the Java 'jnlp' file that should launch the PowerTeacher Gradebook gets associated with TextEdit instead of the correct Mac application. You may see a text file similar to the one below:


To fix it, we need to remind your computer what it should use to open Java files (in geek-speak we want to re-register JNLP files with Java Web Start.app):

1. In the Finder, open the /System/Library/CoreServices folder. According to Apple, simply opening this CoreServices folder should re-associate JNLP files with Java Web Start.app.
(in peoplespeak, open MacHD then open System then Library then CoreServices)
2. Close the CoreServices Finder window.
3. Reboot your computer, then launch the PowerTeacher Gradebook.

If the above steps do not correct the problem, please use this alternative method:

1. Locate a file with the extension .jnlp (use this sample file named player.jnlp, download this file to your computer's desktop before continuing)
2. Right-click on the .jnlp file and select Get Info.
3. For Open With, choose the Java Web Start application: /System/Library/CoreServices/Java Web Start.app (example screen shot below)
4. Click Change All...
5. Click Continue to apply the change to all .jnlp applications.
6. Close the Get Info window.
7. Reboot your computer, then launch the PowerTeacher Gradebook.
