My employer purchased a single copy of Adobe CS6 Premium for my use. I have a valid serial number. But when I try to license the software, I receive a message that the serial number is invalid.

The serial numbers are product and language specific. My first guess woudl be that perhaps you've chosen another language while installing.
Do you have discs or was this an online download? Difficult to say without knowing the details.
\But coudl you have a look at thhis document. Reading it may help you figure out what the issue might be: http://helpx.adobe.com/creative-suite/kb/error-serial-number-valid-pro duct.htm
