I purchased CS5.5 for my laptop (Macbook Pro 2011 ) and now have the newest iMac without a disc drive. I have tried installation via thunderbolt cable but it did not work (getting "error6"when i try to access). How can I install it? Any help is greatly appreciated! Thanks!
You can try downloading the Trial version from here and activatingthat with your serial number
Follow the Very Important Instructions on that page first otherwise the links won't work.
Please see http://forums.adobe.com/message/4644530#4644530 which discusses obtaining your serial number from your product code. Also if you have previously registered your CS5.5 software then you can also review http://forums.adobe.com/message/3987968#3987968?promoid=KBHJW for information on how to locate the serial number under your account.
