Khan Desktop can download and install application updates from SourceForge.net.
From the Setup / Update Application menu item, press the Check For Updates button.
To cancel the Check, press the Cancel button.
If an update is available, press the Install Update button to install, or press the Done button to quit.
You will be required to log on as an administrator to install the update.
If you will not be able to do so, press the Done button and have an administrator install the update for you.
You must restart Khan Desktop to Activate the installed update.
When checking for an update, you may get the message "An update cannot be found on the server". This may happen if SourceForge is busy. Check again some time later.
After restarting Khan Desktop, you may need to update the Topics in the Contents Tab to remove any errors from the previous version. Do so via the Update Tab.
