There is a Mac and a Windows version, so be sure you have the correct one. Assume the student version will not load as it does not accept your s/n.
Do you have a trial version of CS6 loaded on computer?
I have the Windows version. It says it on the box. No, I haven't clicked the trial version. If it won't accept my SN then, what is there to activate it?
It's my first time using Photoshop so I'm kind of troubled here.
Call Adobe Support tomorrow and let them sort it out. Have them check the serial number to make sure it is valid. If not the copy you has either incorrect s/n assigned for a student version, or it is a counterfeit product. Keep your receipt.
I have the same problem and I would like to know where to find the phone number for Adobe Support to talk about my possible counterfeit version. Please reply with a phone number. Thank you.
