To whom it may concern,
Bought Acrobe Creative Suite 6 Design & Web Premium Education edition several years ago and it functioned pretty normal for several years. Yet, Arcobat X Pro suddenly said it would expire several months ago. Tried re-installation and re-input of serial no. several times but it didn't work. Now whenever I start the Arcobat X Pro, there is a prompt showing it has expired.When I try inputing my serial number, it however says, ''This serial number is not valid for this product.'' Ironically, all other applications like photoshops and AI are still functioning normally.
Looking forward to your generous support >.<
Thanks and Regards,
Sorry for the delayed response and inconvenience caused. As per the description above, you are not able to activate the Acrobat Pro 10 which is a part of CS 6 Suite "Design & Web Premium", Is that correct?
Please refer to the following KB doc for the activation issue Error: "The serial number is not valid for this product" | Adobe Creative Suite Link: https://helpx.adobe.com/creative-suite/kb/error-serial-number-valid-product.html
