Set my own key for activation in Visual Studio billing offline software code

I have full source code of Medical billing software(offline), and i want to set my own activation key, and admin password, I do not have any activation key for the software right now. If anyone can change the activation key for me then let me know. I will send the visual studio based source code for medical store billing. I exported the exe file I am attaching. You can test and let me know if you can crack and replace my activation key instead. Debug file attached for testing.
