    You must extract the .slf file from the .zip file before you can use it to activate your product license.

Thats what i was referring to You cannot use SEP 11.0 Enterprise edition license to Small business license.

Your M737 serial number corresponds to Symantec endpoint enterprise edition

You should select M3851 not M737.
