What do I do if I have QuickTime installed, but nothing plays?
- Windows XP
- Windows Vista
Check QuickTime's settings and make sure it is configured to play MIDI files in your browser.
- Open QuickTime and go to Edit > Preferences > QuickTime Preferences.
- Open the Browser tab.
- In the bottom of the resulting window, click the MIME Settings button. The other options on this screen will not affect how Wolfram|Alpha uses QuickTime.
- Expand "Audio - Audio only file formats", and check the option "MIDI file". If it is already checked, uncheck and recheck the option. This will cause QuickTime to reregister itself with your browser. The other MIME types on this screen can be ignored.
- Click OK.
- Close the windows.
- Restart your browser.
