licence Systems software

Hi I have a tracking web application I want to create a license system. First thing, I wish to make this application easy to install: Click on the exe to install database and services .... then, the file generates a single license license from the server. this license will be added on my server to activate the license, in case the client change of server the license crashes. thank you to send me your proposal as well as the final price for this service. thank you for setting the final price.
