Hi there,
Since I have been suffering from this problem for a long time, but I finally reached a solution to this problem, and I use it to protect my own programs.
I can protect your program as an experiment, and if the protection meets your desire, you could hire me.
But you have to believe that there is no complete protection (there is NO 100% protection). Even with the largest companies like Microsoft, their Windows system is being cracked.
I have more than 15 years of c# and desktop applications experience.
Please send me a message so that we can discuss further.
Sincerely
Joseph
