how to get aperture serial number
plz help me my aperture cannot open . how to get serial number aperture
Aperture 3, OS X Mountain Lion (10.8.2)
The article you came from (Pro Application Replacement Serial Numbers) tells exactly how to apply for a replacement serial number, if you do no longer have it. Only Apple can give you a replacement.
How did you buy Aperture? The boxed retail version? Then the serial number is in/on the box. If you bought online and unlocked the trial version with a serial number, you need to find the email with the serial number.
If you bought from the App Store, there is no serial number. If Aperture is asking for one, you need to reinstall from the AppStore.
But if you have a serial number, but Aperture does not accept it, check the number you are entering for letters that can be confused, like O and 0, see: Troubleshooting Professional Application Serial Numbers
