You receive an "iShell has encountered a problem" message or experience display problems

Some users have reported problems such as an "iShell has encountered a problem" message or strange display problems when running the program. These problems were the result of corrupted QuickTime files, which are easily rectified by uninstalling QuickTime and reinstalling from the program disc.

If you have trouble uninstalling QuickTime, check out this article on QuickTime Windows troubleshooting tips from Apple's web site.

Or, try the following;


When I launch the program, I get an error saying QuickTime is required even though I have the latest version of QuickTime already installed.
You may encounter this message when you first launch the program if you have the latest version of QuickTime. We are working on a fix for this. In the meantime, we have a separate page outlining a workaround that allows you to run the program normally.
