Customer Question

Tryin to install my upgrade CS5.5, from CS 2 premium, to my iMac OS X version 10.10.3. I understand I need to get on CC 7. At the moment however, I want to install this product. I have the serial numbers, but for some reason Adobe doesn't recognize them. Any help? thanks.

Hi there,
if you get a message that the serial number is ***** try uninstalling everything first and then do a clean re-install. If you still get the invalid serial number message, then you will need to contact Adobe Support:
