I provide you stable and secured code as well, everything can be cracked so don't be sure that there is a program or a tool that can make you 100% secured, but at least should be little a bit hard, anyway, i already have some codes in C# that i made which makes any tool to be using trial time and re-active with License as well, so i can edit the code, so it get that license from Internet, so you can set up licenses online as well!
Thanks for your attention!
