I was cleaning some stuff off my hard drive the other day, and ever since then, every time I open Aperture, a "Licensing" window comes up asking for my name, organization, and serial number. 


I enter the serial number, and everything works (and my library and all of my pics are still there).  But if I close Aperture, the Licensing window pops up the next time I open Aperture.


Can anyone tell me what's going on?  I was pretty sure everything I was deleting from my hard drives was fine to delete, but the timing can't be a coincidence.


How can I fix this?

    What is your Aperture version? Is your signature (iMac (27-inch Mid 2010), Mac OS X (10.6.4)) still current?


    Cleaning up should not cause this problem. Or did you clean up your System Library?


    How are you entering the serial number? Aperture is installed for all users on your mac, so the serial number is written to the System Library, not your User Library, and this requires read/write access for administrators. Do you enter your serial number using an administrator account?


    Also, you may have a corrupted "ProAppSystemID" file or Aperture cannot write to the System Library.


    To stop Aperture asking for the serial number, first check, if you still have an old file "ProAppSystemID" in your System Library.


    • Quit Aperture.
    • Go to your MacintoshHD and open the folder "Library", then "Application Support", then "ProApps".
    • Remove the File "ProAppsSystemID" to the Desktop, if it exist and restart Aperture.
    • Reenter your serial number, hopefully for the last time.


    Sometimes Aperture writes this file to a temporary directory, when it cannot write to the Library. If the above does not work, look at the temporary directory /tmp


    • Use the Finder's "Go" menu

         Go > Got to folder    and  enter /tmp into the textfield. If you see the file there, move it to its proper location.

    Apple just issued an Aperture update (3.4.3), that should fix exactly your problem.

    Thanks for the responses.  I was going to try leonieDF's, but it looked like quite an endeavor.  Thanks for saving me all that time!

    Did it work?

  • JDLee Level 1 (5 points)

    Yes, that's why I marked it solved.  But maybe that wasn't clear.  I started Aperture after the update, it prompted me for my serial number again, I entered it.  I then opened and closed it twice without it prompting me again, so it seems solved.

    What a relief that this is finally fixed with the new update!

    Great news!

  • JDLee Level 1 (5 points)

    Oh, so this was a problem some people were experiencing, and this fixed it?  Your solution probably would have worked.  I just got lucky on the timing, I guess.

    It has been a problem, ever since I first started to browse this forum. I wonder, how they fixed it, and where the serial number will be stored now

    I have just done the upgrading and was still prompt with the serial number. But I bought the software online an cannot seem to find the serial number anywhere.....Can anyone advise?

    You may try to remove Aperture completely from computer including all the preferences files and then redownload it from App Store.

    Hi Munas,


    Many thanks. It works. Cheers.

    Alas, I'm still being prompted for a serial number after the upgrade.  My version of aperture was not purchased through the App Store.

  • Aye Es Oh Level 2 (330 points)

    Nano_person, did you try deleting Aperture and reinstalling it from your original media?

    I have the same problem with having to re-enter Serial # everytime I launch Aperture.  I also migrated to a new computer which is when the problem began.  Your post is very helpful.  I checked the /Library/Application Support/ProApps folder and did not find a ProAppsSystemID file.  Per you advice, I checked the /tmp folder and did find the file there.  BTW, I'm running version 3.4.5, version 3.4.3 doesn't seem to have solved the problem.  Is this a permissions problem or is there anything else I can do from this point? 


    I also purchased Aperture prior to the App store and a few versions ago, so reloading from scratch would be difficult.  Any suggestion would be appreciated.
