Hi,

A quick search using the search tool here, or with Google Search, returns many hits. One of the first told me the following:

Troubleshooting "Error code -14"

You successfully installed your software, but you still receive the message "Error code -14" when you try to register it.

To solve your problem, first check the indicated serial number for typos. In case you purchased several applications at the same time, please check if you were using the serial number matching to the program.

Various retailers distribute the software using the POSA procedure. 
The serial numbers only become valid when they are activated via the seller's POS system. 
If the serial number is not activated through the POS system, it cannot be used.

If you purchased the software from a retail location, you will need to visit the shop again to solve the problem.

if that does not help you to fix your problem, study the other hits. And failing that, post again with much more information, as requested in the prominent sticky at the top of the page.
