Ultimate package

I have recently acquired  the ultimate package, but have been struggling to install the package.
The following error message keep coming up.
-  AVG  is unable to recognised the license number
-  The license is not valid or the license information is not found
It is very frustrating for someone not to clued up on computers,  and installed the program for protection.
Someone please  advise urgently.
