Why are the menu options, "Movie, Video Capture, and Gel Analysis" grayed out in the Insert menu of Logger Pro?

This is a Windows-only issue.

The Movie, Video Capture, and Gel Analysis features of the Insert menu of Logger Pro 3 require QuickTime to be installed on your computer.

If the options to insert a Movie, Video Capture, or Gel Analysis are greyed-out, this indicates that QuickTime is not installed properly.

Please download the latest version of QuickTime and use the installer to update or repair your QuickTime installation. To do this, visit the Apple QuickTime page:
