Installation Failed

[Guest]

I just bought the CS6 upgrade for my CS5 PS.  I bought the upgrade from the Adobe site.  Installation fails and says that the upgrae I am trying to install is not a genuine Adobe product.  I have entered the serial number exactly and it is verified.  I have no idea what to do.

You can ignore this message and try to download the product using the Alternate method from the Adobe Account else download the product from http://www.adobe.com/downloads/
