So I'm taking my Mac to the Apple store today for a COMPLETE Operating System Restore. I won't be backing up any data because I don't have an external Hardrive. :/ Anyways that doesn't matter MY QUESTION: I have bought Adobe Master Suite CS4 and Microsoft Office 2008. How do I de authorize these products so I can use the serial # again? I don't want to waste a serial number just because Im restoring my computer..... I have all the original install disc & Serials for both of the software (MS Office & Adobe MS CS4) So please tell me what I need to do to use the Serial # again. Please & Thank you.
