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;

  • Download and install the Windows Installer CleanUp utility.
  • Run the Utility ("Start > All Programs > Windows Install Clean Up"), find any QuickTime entries in the list of programs that appear in CleanUp, select the QuickTime entries, and then click “Remove”.
  • Next, manually remove leftover program files and folders if you have not already done this.

    A. Remove QuickTime program files:

    1. On the Start menu, click My Computer (or double-click My Computer on the Desktop).
    2. In My Computer, open Local Disk.
    3. Open Program Files.
    4. Right-click on the QuickTime folder and click Delete from the shortcut menu.

    B. Remove QuickTime system files

    1. Navigate to C:\Windows\system32\.
    2. Remove the files QuickTime.qts and QuicktimeVR.qtx. (If “Hide filename extensions for known file types” is enabled on the PC, then those two files will appear as “QuickTime” and QuickTimeVR”.)

    C. Restart your computer and check that QuickTime is gone from Add/Remove programs.


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.
