Color Engine Pilot fails to start up after Internet Explorer is updated to version 10.


On some Windows systems, the Windows Update service will trigger an update of Internet Explorer to Internet Explorer 10.  As a consequence, Color Engine Pilot will not start up correctly.

A process with the name kaleidoscope.exe will be listed in the processes list in Windows Task Manager, but the standard/usual interface of Color Engine Pilot will not appear.


If Internet Explorer 10 is installed, uninstall it by doing the following:

  1. Click the Start button.
  2. In the search box, type Programs and Features.
  3. Click Programs and Features.
  4. Select View installed updates in the left pane.
  5. Under Uninstall an update, scroll down to the Microsoft Windows section.
  6. Right-click Internet Explorer 10 and click Uninstall.
  7. Click yes, when the confirmation prompt appears and then follow the instructions on the screen.
  8. Click one of the following:
    1. Restart now (to finish the process of uninstalling Internet Explorer 10 and restore the previous version of Internet Explorer)
    2. Restart later.

Internet Explorer 8 or 9 will be available on the system after you have restarted the system.


To prevent similar issues, we recommend you to change the Windows Update configuration to Download updates for me, but let me choose when to install.
