The U on iTunes U - Troubleshooting
Logging into iTunes U opens iTunes website
This happens when you try to login into iTunes U but do not have iTunes application installed. The page you were redirected to is the site from which you can download iTunes. Currently, you must download and install iTunes in order to use iTunes U.
In the future we plan on developing support that allows any RSS aggregator to access iTunes U content.
Firefox displays message when logging iTunes U
When this error message appears on Windows...
Or the error message appears...
Firefox needs to be properly configured to open URLs that are supposed to be handled by iTunes (prefix for these URLs is itms:// or itmss:// ).
Firefox has security checks which may prevent it from launching a helper application such as iTunes. The first time Firefox attempts to open one of these URLs, it will prompt the user with a panel asking if they are sure they want to use this helper application. If the user chooses not to use the helper application, then they will not have the abiility to transition from Firefox into iTunes U or the iTunes Music Store. Secondarily, Firefox for the Mac does not render this panel correctly if the URL is too long and the user may not be able to enter iTunes U.
You first can try selecting "Remeber my choice for all links of this type" and it shouldn't display this error message in the future.
If they need to reset Firefox, then follow these instructions:
Enter "about:config" in the address bar, which will
open the advance configuration options of Firefox.
In the text field labeled "Filter" enter 'itms'
Look for items with the Preference Name that start with 'network.protocol-handler'
If the value is "true" double-click on the line and it should
change to "false". Then you shouldn't get any more
error messages when acessing iTunes U with Firefox.
Internet Explorer 6 & 7 Security Warning
When logging into iTunes U using Internet Explorer 6 or 7, you
might have a message display that "This page contains both
secure and nonsecure items".
If you click the "Yes" button
iTunes U should load properly.
