Logic 9 Serial Number Not Valid

I recently backed up my computer and did a complete OS reinstall (starting from stratch and not using the old image due to old corruption files). I then decided to manualy copy over Logic Pro 9 files from the backup drive to the new image. I went to open Logic and it asked for my serial number. I typed it in and then it decided to crash on me. Well no big deal, I probably didn't copy all the files. So I deleted as many files as I could find and then proceded to reinstalling Logic 9 from my Logic Studio disc set. Entered name and the serial key during the beggining of the install and it says "Serial Number Not Valid" and asked me to type it again and gives me the same message. After 3 failed attempts, it closes the installation program. I have tripple checked my spelling in the key and have checked forums regarding this problem. I have already attempted to move the ID files in Library/Application Support/ProApps to the desktop; no change. Any input would be nice. Thank you.


I am running Mavericks 10.9.1 on a MacBook pro 2012.

Was your copy of Logic Studio 2.0 (the one containing LP9) a full version or an upgrade version?


If it was an upgrade version you need to enter your original LP8 serial first.... and then it will ask for your LP9 upgrade serial...


If it was the full version, contact Apple directly and ask for their assistance.

Note: Once you have successfully installed LP9.. you must upgrade LP9 to the latest version 9.1.8 before you run it, via software updates... as you are running Mavericks...
