"I've lost my QuickTime Pro registration key(s). What should I do?

You can retrieve purchased registration keys this way:

1. Visit the Apple Online Store.
2. Cick "Account" in the upper-right corner.
3. Click "Downloadable Software Purchases".
4. Enter your Apple ID and password.

You should see your QuickTime Pro registration key(s)."

This functionality is missing. How do I find my old license codes?
