There are pieces to the puzzle missing. More information would be helpful to finding the solution.
Do you have a compatible version of software? What error message are you getting?
How are you trying to load the software; download, zip file, or CD?
Have you previously loaded this version onto another computer? You may need a special code to allow the software to run on a different computer.
There should be a support phone number for the software. Support can help with these types of issues. If you purchased from a dealer, there may be someone that can assist you also.
Good luck!
