I bought last year Creative Suite 5.5 and I received a gift of the CS6. Now I am prompted to register again for CS6 but by entering the serial number is returned me the error of serial number is not valid.
How should I proceed??
and you should be able to resolve the concern.
You might have received 2 serial numbers, one for CS5.5 and other for CS6. So, make sure you type the serial number you received for CS6 first and then for CS5.5.
On which OS are actually trying to install CS6? Attach the error screenshot, in case of same issue.
Prismagraf, i have removed the serial key screenshot that you posted. Please do not post your serial keys and contact details in public.
Also, i have sent you a private message. Check that and revert.
I just checked the serials that you sent me and both of them are valid serials and you should not get that error.
From where are you installing it? What all adobe applications do you have on the machine?
Hmn. Might be an issue with the setup. Install the product from the desktop and check : "http://helpx.adobe.com/creative-suite/kb/install-creative-suite-5-cs5. html"
Also, in case same issue, download a trial version of CS6 from adobe.com and try to install.
Check if it helps.
